This function extracts the PRE_SI_PLATFORM field from the HIDREV
register and can be used to determine which platform the kernel runs on
(silicon, simulation, ...). Note that while only Tegra194 and later
define this field, it should be safe to call this on prior generations
as well since this field should read as 0, indicating silicon.

eznps driver is supposed to be platform independent however it ends up
including stuff from inside arch/arc headers leading to rand config
build errors.
The quick hack to fix this (proper fix is too much chrun for non active
user-base) is to add following to nps platform agnostic header.
- copy AUX_IENABLE from arch/arc header
- move CTOP_AUX_IACK from arch/arc/plat-eznps/*/**

framework we just have some minor tweaks and a debugfs feature, so not much to
see there. The driver updates are fairly well split between AT91 and Qualcomm
clk support. Adding those two drivers together equals about 50% of the
diffstat. Otherwise, the big amount of work this time was on supporting
Broadcom's Raspberry Pi firmware clks. See below for some more highlights.
Core:
- Document clk_hw_round_rate() so it gets some more use
- Remove unused __clk_get_flags()
- Add a prepare/enable debugfs feature similar to rate setting
New Drivers:
- Add support for SAMA7G5 SoC clks
- Enable CPU clks on Qualcomm IPQ6018 SoCs
- Enable CPU clks on Qualcomm MSM8996 SoCs
- GPU clk support for Qualcomm SM8150 and SM8250 SoCs
- Audio clks on Qualcomm SC7180 SoCs
- Microchip Sparx5 DPLL clk
- Add support for the new Renesas RZ/G2H (R8A774E1) SoC
Updates:
- Make defines for bcm63xx-gate clks to use in DT
- Support BCM2711 SoC firmware clks
- Add HDMI clks for BCM2711 SoCs
- Add RTC related clks on Ingenic SoCs
- Support USB PHY clks on Ingenic SoCs
- Support gate clks on BCM6318 SoCs
- RMU and DMAC/GPIO clock support for Actions Semi S500 SoCs
- Use poll_timeout functions in Rockchip clk driver
- Support Rockchip rk3288w SoC variant
- Mark mac_lbtest critical on Rockchip rk3188
- Add CAAM clock support for i.MX vf610 driver
- Add MU root clock support for i.MX imx8mp driver
- Amlogic g12: add neural network accelerator clock sources
- Amlogic meson8: remove critical flag for main PLL divider
- Amlogic meson8: add video decoder clock gates
- Convert one more Renesas DT binding to json-schema
- Enhance critical clock handling on Renesas platforms to only consider
clocks that were enabled at boot time

Add support for retrieving BPMP debug information via in-band messaging
as opposed to using shared-memory which older BPMP firmware used. Note
that it is possible to detect at runtime whether the BPMP firmware being
used supports the in-band messaging for retrieving the debug
informaation. Therefore, if the BPMP firmware supports the in-band
messaging for debug use this and otherwise fall-back to using shared
memory.

The ocelot_wm_encode function deals with setting thresholds for pause
frame start and stop. In Ocelot and Felix the register layout is the
same, but for Seville, it isn't. The easiest way to accommodate Seville
hardware configuration is to introduce a function pointer for setting
this up.

With this patch we try to kill 2 birds with 1 stone.
First of all, some switches that use tag_ocelot.c don't have the exact
same bitfield layout for the DSA tags. The destination ports field is
different for Seville VSC9953 for example. So the choices are to either
duplicate tag_ocelot.c into a new tag_seville.c (sub-optimal) or somehow
take into account a supposed ocelot->dest_ports_offset when packing this
field into the DSA injection header (again not ideal).
Secondly, tag_ocelot.c already needs to memset a 128-bit area to zero
and call some packing() functions of dubious performance in the
fastpath. And most of the values it needs to pack are pretty much
constant (BYPASS=1, SRC_PORT=CPU, DEST=port index). So it would be good
if we could improve that.
The proposed solution is to allocate a memory area per port at probe
time, initialize that with the statically defined bits as per chip
hardware revision, and just perform a simpler memcpy in the fastpath.
Other alternatives have been analyzed, such as:
- Create a separate tag_seville.c: too much code duplication for just 1
bit field difference.
- Create a separate DSA_TAG_PROTO_SEVILLE under tag_ocelot.c, just like
tag_brcm.c, which would have a separate .xmit function. Again, too
much code duplication for just 1 bit field difference.
- Allocate the template from the init function of the tag_ocelot.c
module, instead of from the driver: couldn't figure out a method of
accessing the correct port template corresponding to the correct
tagger in the .xmit function.

Currently Felix and Ocelot share the same bit layout in these per-port
registers, but Seville does not. So we need reg_fields for that.
Actually since these are per-port registers, we need to also specify the
number of ports, and register size per port, and use the regmap API for
multiple ports.
There's a more subtle point to be made about the other 2 register
fields:
- QSYS_SWITCH_PORT_MODE_SCH_NEXT_CFG
- QSYS_SWITCH_PORT_MODE_INGRESS_DROP_MODE
which we are not writing any longer, for 2 reasons:
- Using the previous API (ocelot_write_rix), we were only writing 1 for
Felix and Ocelot, which was their hardware-default value, and which
there wasn't any intention in changing.
- In the case of SCH_NEXT_CFG, in fact Seville does not have this
register field at all, and therefore, if we want to have common code
we would be required to not write to it.

Add the register definitions for the MSCC MIIM MDIO controller in
preparation for seville_vsc9959.c to create its accessors for the
internal MDIO bus.
Since we've introduced elements to ocelot_regfields that are not
instantiated by felix and ocelot, we need to define the size of the
regfields arrays explicitly, otherwise ocelot_regfields_init, which
iterates up to REGFIELD_MAX, will fault on the undefined regfield
entries (if we're lucky).

At the moment, there are some minimal register differences between
VSC7514 Ocelot and VSC9959 Felix. To be precise, the PCS1G registers are
missing from Felix because it was integrated with an NXP PCS.
But with VSC9953 Seville (not yet introduced), the register differences
are more pronounced. The MAC registers are located at different offsets
within the DEV_GMII target. So we need to refactor the driver to keep a
regmap even for per-port registers. The callers of the ocelot_port_readl
and ocelot_port_writel were kept unchanged, only the implementation is
now more generic.

Let's rename the structures and functions to something more generic, so
that VCAP IS1 structures (which would otherwise have to be called
Ingress Classification Entries) can reuse the same code without
confusion.
Some renaming that was done:
struct ocelot_ace_rule -> struct ocelot_vcap_filter
struct ocelot_acl_block -> struct ocelot_vcap_block
enum ocelot_ace_type -> enum ocelot_vcap_key_type
struct ocelot_ace_vlan -> struct ocelot_vcap_key_vlan

The current codebase makes use of one-element arrays in the following
form:
struct something {
int length;
u8 data[1];
};
struct something *instance;
instance = kmalloc(sizeof(*instance) + size, GFP_KERNEL);
instance->length = size;
memcpy(instance->data, source, size);
but the preferred mechanism to declare variable-length types such as
these ones is a flexible array member[1][2], introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on. So, replace
the one-element array with a flexible-array member.
Also, make use of the new struct_size() helper to properly calculate the
size of struct qe_firmware.
This issue was found with the help of Coccinelle and, audited and fixed
_manually_.

The Raspberry Pi 4 gets its USB functionality from VL805, a PCIe chip
that implements xHCI. After a PCI reset, VL805's firmware may either be
loaded directly from an EEPROM or, if not present, by the SoC's
co-processor, VideoCore. RPi4's VideoCore OS contains both the non public
firmware load logic and the VL805 firmware blob. The function this patch
introduces triggers the aforementioned process.

When running 'bridge fdb dump' on Felix, sometimes learnt and static MAC
addresses would appear, sometimes they wouldn't.
Turns out, the MAC table has 4096 entries on VSC7514 (Ocelot) and 8192
entries on VSC9959 (Felix), so the existing code from the Ocelot common
library only dumped half of Felix's MAC table. They are both organized
as a 4-way set-associative TCAM, so we just need a single variable
indicating the correct number of rows.

This patch is to move current ptp clock code out of ocelot.c driver
maintaining as a single ocelot_ptp.c.
For futher new features implementation, the common code could be put
in ocelot_ptp.c and the switch specific code should be in specific
switch driver. The interrupt implementation in SoC is different

To rehash a previous explanation given in commit 1c44ce560b ("net:
mscc: ocelot: fix vlan_filtering when enslaving to bridge before link is
up"), the switch driver operates the in a mode where a single VLAN can
be transmitted as untagged on a particular egress port. That is the
"native VLAN on trunk port" use case.
The configuration for this native VLAN is driven in 2 ways:
- Set the egress port rewriter to strip the VLAN tag for the native
VID (as it is egress-untagged, after all).
- Configure the ingress port to drop untagged and priority-tagged
traffic, if there is no native VLAN. The intention of this setting is
that a trunk port with no native VLAN should not accept untagged
traffic.
Since both of the above configurations for the native VLAN should only
be done if VLAN awareness is requested, they are actually done from the
ocelot_port_vlan_filtering function, after the basic procedure of
toggling the VLAN awareness flag of the port.
But there's a problem with that simplistic approach: we are trying to
juggle with 2 independent variables from a single function:
- Native VLAN of the port - its value is held in port->vid.
- VLAN awareness state of the port - currently there are some issues
here, more on that later*.
The actual problem can be seen when enslaving the switch ports to a VLAN
filtering bridge:
0. The driver configures a pvid of zero for each port, when in
standalone mode. While the bridge configures a default_pvid of 1 for
each port that gets added as a slave to it.
1. The bridge calls ocelot_port_vlan_filtering with vlan_aware=true.
The VLAN-filtering-dependent portion of the native VLAN
configuration is done, considering that the native VLAN is 0.
2. The bridge calls ocelot_vlan_add with vid=1, pvid=true,
untagged=true. The native VLAN changes to 1 (change which gets
propagated to hardware).
3. ??? - nobody calls ocelot_port_vlan_filtering again, to reapply the
VLAN-filtering-dependent portion of the native VLAN configuration,
for the new native VLAN of 1. One can notice that after toggling "ip
link set dev br0 type bridge vlan_filtering 0 && ip link set dev br0
type bridge vlan_filtering 1", the new native VLAN finally makes it
through and untagged traffic finally starts flowing again. But
obviously that shouldn't be needed.
So it is clear that 2 independent variables need to both re-trigger the
native VLAN configuration. So we introduce the second variable as
ocelot_port->vlan_aware.
*Actually both the DSA Felix driver and the Ocelot driver already had
each its own variable:
- Ocelot: ocelot_port_private->vlan_aware
- Felix: dsa_port->vlan_filtering
but the common Ocelot library needs to work with a single, common,
variable, so there is some refactoring done to move the vlan_aware
property from the private structure into the common ocelot_port
structure.

Ocelot has 384 policers that can be allocated to ingress ports,
QoS classes per port, and VCAP IS2 entries. ocelot_police.c
supports to set policers which can be allocated to police action
of VCAP IS2. We allocate policers from maximum pol_id, and
decrease the pol_id when add a new vcap_is2 entry which is
police action.

Changing the MTU for this switch means altering the
DEV_GMII:MAC_CFG_STATUS:MAC_MAXLEN_CFG field MAX_LEN, which in turn
limits the size of frames that can be received.
Special accounting needs to be done for the DSA CPU port (NPI port in
hardware terms). The NPI port configuration needs to be held inside the
private ocelot structure, since it is now accessed from multiple places.

What the driver writes into MAC_MAXLEN_CFG does not actually represent
VLAN_ETH_FRAME_LEN but instead ETH_FRAME_LEN + ETH_FCS_LEN. Yes they are
numerically equal, but the difference is important, as the switch treats
VLAN-tagged traffic specially and knows to increase the maximum accepted
frame size automatically. So it is always wrong to account for VLAN in
the MAC_MAXLEN_CFG register.
Unconditionally increase the maximum allowed frame size for
double-tagged traffic. Accounting for the additional length does not
mean that the other VLAN membership checks aren't performed, so there's
no harm done.
Also, stop abusing the MTU name for configuring the MRU. There is no
support for configuring the MRU on an interface at the moment.

Compared to other DSA switches, in the Ocelot cores, the RX filtering is
a much more important concern.
Firstly, the primary use case for Ocelot is non-DSA, so there isn't any
secondary Ethernet MAC [the DSA master's one] to implicitly drop frames
having a DMAC we are not interested in. So the switch driver itself
needs to install FDB entries towards the CPU port module (PGID_CPU) for
the MAC address of each switch port, in each VLAN installed on the port.
Every address that is not whitelisted is implicitly dropped. This is in
order to achieve a behavior similar to N standalone net devices.
Secondly, even in the secondary use case of DSA, such as illustrated by
Felix with the NPI port mode, that secondary Ethernet MAC is present,
but its RX filter is bypassed. This is because the DSA tags themselves
are placed before Ethernet, so the DMAC that the switch ports see is
not seen by the DSA master too (since it's shifter to the right).
So RX filtering is pretty important. A good RX filter won't bother the
CPU in case the switch port receives a frame that it's not interested
in, and there exists no other line of defense.
Ocelot is pretty strict when it comes to RX filtering: non-IP multicast
and broadcast traffic is allowed to go to the CPU port module, but
unknown unicast isn't. This means that traffic reception for any other
MAC addresses than the ones configured on each switch port net device
won't work. This includes use cases such as macvlan or bridging with a
non-Ocelot (so-called "foreign") interface. But this seems to be fine
for the scenarios that the Linux system embedded inside an Ocelot switch
is intended for - it is simply not interested in unknown unicast
traffic, as explained in Allan Nielsen's presentation [0].
On the other hand, the Felix DSA switch is integrated in more
general-purpose Linux systems, so it can't afford to drop that sort of
traffic in hardware, even if it will end up doing so later, in software.
Actually, unknown unicast means more for Felix than it does for Ocelot.
Felix doesn't attempt to perform the whitelisting of switch port MAC
addresses towards PGID_CPU at all, mainly because it is too complicated
to be feasible: while the MAC addresses are unique in Ocelot, by default
in DSA all ports are equal and inherited from the DSA master. This adds
into account the question of reference counting MAC addresses (delayed
ocelot_mact_forget), not to mention reference counting for the VLAN IDs
that those MAC addresses are installed in. This reference counting
should be done in the DSA core, and the fact that it wasn't needed so
far is due to the fact that the other DSA switches don't have the DSA
tag placed before Ethernet, so the DSA master is able to whitelist the
MAC addresses in hardware.
So this means that even regular traffic termination on a Felix switch
port happens through flooding (because neither Felix nor Ocelot learn
source MAC addresses from CPU-injected frames).
So far we've explained that whitelisting towards PGID_CPU:
- helps to reduce the likelihood of spamming the CPU with frames it
won't process very far anyway
- is implemented in the ocelot driver
- is sufficient for the ocelot use cases
- is not feasible in DSA
- breaks use cases in DSA, in the current status (whitelisting enabled
but no MAC address whitelisted)
So the proposed patch allows unknown unicast frames to be sent to the
CPU port module. This is done for the Felix DSA driver only, as Ocelot
seems to be happy without it.

Ocelot has the concept of a CPU port. The CPU port is represented in the
forwarding and the queueing system, but it is not a physical device. The
CPU port can either be accessed via register-based injection/extraction
(which is the case of Ocelot), via Frame-DMA (similar to the first one),
or "connected" to a physical Ethernet port (called NPI in the datasheet)
which is the case of the Felix DSA switch.
In Ocelot the CPU port is at index 11.
In Felix the CPU port is at index 6.
The CPU bit is treated special in the forwarding, as it is never cleared
from the forwarding port mask (once added to it). Other than that, it is
treated the same as a normal front port.
Both Felix and Ocelot should use the CPU port in the same way. This
means that Felix should not use the NPI port directly when forwarding to
the CPU, but instead use the CPU port.
This patch is fixing this such that Felix will use port 6 as its CPU
port, and just use the NPI port to carry the traffic.
Therefore, eliminate the "ocelot->cpu" variable which was holding the
index of the NPI port for Felix, and the index of the CPU port module
for Ocelot, so the variable was actually configuring different things
for different drivers and causing at least part of the confusion.
Also remove the "ocelot->num_cpu_ports" variable, which is the result of
another confusion. The 2 CPU ports mentioned in the datasheet are
because there are two frame extraction channels (register based or DMA
based). This is of no relevance to the driver at the moment, and
invisible to the analyzer module.

The IGR_PORT_MASK key width is different between the 11-port VSC7514 and
the 6-port VSC9959 switches. And since IGR_PORT_MASK is one of the first
fields of a VCAP key entry, it means that all further field
offset/length pairs are shifted between the 2.
The ocelot driver performs packing of VCAP half keys with the help of
some preprocessor macros:
- A set of macros for defining the HKO (Half Key Offset) and HKL (Half
Key Length) of each possible key field. The offset of each field is
defined as the sum between the offset and the sum of the previous
field.
- A set of accessors on top of vcap_key_set for shorter (aka less
typing) access to the HKO and HKL of each key field.
Since the field offsets and lengths are different between switches,
defining them through the preprocessor isn't going to fly. So introduce
a structure holding (offset, length) pairs and instantiate it in
ocelot_board.c for VSC7514. In a future patch, a similar structure will
be instantiated in felix_vsc9959.c for NXP LS1028A.
The accessors also need to go. They are based on macro name
concatenation, which is horrible to understand and follow.

The ocelot tc-flower offload binds a second flow block callback (apart
from the one for matchall) just because it uses a different block
private structure (ocelot_port_private for matchall, ocelot_port_block
for flower).
But ocelot_port_block just appears to be boilerplate, and doesn't help
with anything in particular at all, it's just useless glue between the
(global!) struct ocelot_acl_block *block pointer, and a per-netdevice
struct ocelot_port_private *priv.
So let's just simplify that, and make struct ocelot_port_private be the
private structure for the block offload. This makes us able to use the
same flow callback as in the case of matchall.
This also reveals that the struct ocelot_acl_block *block is used rather
strangely, as mentioned above: it is defined globally, allocated at
probe time, and freed at unbind time. So just move the structure to the
main ocelot structure, which gives further opportunity for
simplification.
Also get rid of backpointers from struct ocelot_acl_block and struct
ocelot_ace_rule back to struct ocelot, by reworking the function
prototypes, where necessary, to use a more DSA-friendly "struct ocelot
*ocelot, int port" format.
And finally, remove the debugging prints that were added during
development, since they provide no useful information at this point.

The commit 9209fb5189 ("riscv: move sifive_l2_cache.c to drivers/soc")
moves the sifive L2 cache driver to driver/soc. It did not move the
header file along with the driver. Therefore this patch moves the header
file to driver/soc

The Ocelot switchdev driver and the Felix DSA one need it for different
reasons. Felix (or at least the VSC9959 instantiation in NXP LS1028A) is
integrated with the traditional NXP Layerscape PCS design which does not
support runtime configuration of SerDes protocol. So it needs to
pre-validate the phy-mode from the device tree and prevent PHYLINK from
attempting to change it. For this, it needs to cache it in a private
variable.

When building this on a 64-bit platform gcc rightly warns that the
error checking is broken (-ENOMEM stored in an u32 does not compare
greater than (unsigned long)-MAX_ERRNO). Instead, change the
ucc_fast_[tr]x_virtual_fifo_base_offset members to s32 and use an
ordinary check-for-negative. Also, this avoids treating 0 as "this
cannot have been returned from qe_muram_alloc() so don't free it".

When trying to build this for a 64-bit platform, one gets warnings
from using IS_ERR_VALUE on something which is not sizeof(long).
Instead, change the various *_offset fields to store a signed integer,
and simply check for a negative return from qe_muram_alloc(). Since
qe_muram_free() now accepts and ignores a negative argument, we only
need to make sure these fields are initialized with -1, and we can
just unconditionally call qe_muram_free() in ucc_slow_free().
Note that the error case for us_pram_offset failed to set that field
to 0 (which, as noted earlier, is anyway a bogus sentinel value).

Nobody uses the return value from cpm_muram_free, and functions that
free resources usually return void. One could imagine a use for a "how
much have I allocated" a la ksize(), but knowing how much one had
access to after the fact is useless.

There are a number of problems with cpm_muram_alloc() and its
callers. Most callers assign the return value to some variable and
then use IS_ERR_VALUE to check for allocation failure. However, when
that variable is not sizeof(long), this leads to warnings - and it is
indeed broken to do e.g.
u32 foo = cpm_muram_alloc();
if (IS_ERR_VALUE(foo))
on a 64-bit platform, since the condition
foo >= (unsigned long)-ENOMEM
is tautologically false. There are also callers that ignore the
possibility of error, and then there are those that check for error by
comparing the return value to 0...
One could fix that by changing all callers to store the return value
temporarily in an "unsigned long" and test that. However, use of
IS_ERR_VALUE() is error-prone and should be restricted to things which
are inherently long-sized (stuff in pt_regs etc.). Instead, let's aim
for changing to the standard kernel style
int foo = cpm_muram_alloc();
if (foo < 0)
deal_with_it()
some->where = foo;
Changing the return type from unsigned long to s32 (aka signed int)
doesn't change the value that gets stored into any of the callers'
variables except if the caller was storing the result in a u64 _and_
the allocation failed, so in itself this patch should be a no-op.
Another problem with cpm_muram_alloc() is that it can certainly
validly return 0 - and except if some cpm_muram_alloc_fixed() call
interferes, the very first cpm_muram_alloc() call will return just
that. But that shows that both ucc_slow_free() and ucc_fast_free() are
buggy, since they assume that a value of 0 means "that field was never
allocated". We'll later change cpm_muram_free() to accept (and ignore)
a negative offset, so callers can use a sentinel of -1 instead of 0
and just unconditionally call cpm_muram_free().

There are no current callers of these functions, and they use the
ppc-specific virq_to_hw(). So removing them gets us one step closer to
building QE support for ARM.
If the functionality is ever actually needed, the code can be dug out
of git and then adapted to work on all architectures, but for future
reference please note that I believe qe_ic_set_priority is buggy: The
"priority < 4" should be "priority <= 4", and in the else branch 24
should be replaced by 28, at least if I'm reading the data sheet right.

Having to call qe_ic_init() from platform-specific code makes it
awkward to allow building the QE drivers for ARM. It's also a needless
duplication of code, and slightly error-prone: Instead of the caller
needing to know the details of whether the QUICC Engine High and QUICC
Engine Low are actually the same interrupt (see e.g. the machine_is()
in mpc85xx_mds_qeic_init), just let the init function choose the
appropriate handlers after it has parsed the DT and figured it out. If
the two interrupts are distinct, use separate handlers, otherwise use
the handler which first checks the CHIVEC register (for the high
priority interrupts), then the CIVEC.
All existing callers pass 0 for flags, so continue to do that from the
new single caller. Later cleanups will remove that argument
from qe_ic_init and simplify the body, as well as make qe_ic_init into
a proper init function for an IRQCHIP_DECLARE, eliminating the need to
manually look up the fsl,qe-ic node.

The *_ipic and *_mpic handlers are almost identical - the only
difference is that the latter end with an unconditional
chip->irq_eoi() call. Since IPIC does not have ->irq_eoi, we can
reduce some code duplication by calling irq_eoi conditionally.
This is similar to what is already done in mpc8xxx_gpio_irq_cascade().
This leaves the functions slightly misnamed, but that will be fixed in
a subsequent patch.

The QUICC engine drivers use the powerpc-specific out_be32() etc. In
order to allow those drivers to build for other architectures, those
must be replaced by iowrite32be(). However, on powerpc, out_be32() is
a simple inline function while iowrite32be() is out-of-line. So in
order not to introduce a performance regression on powerpc when making
the drivers work on other architectures, introduce qe_io* helpers.
Also define the qe_{clr,set,clrset}bits* helpers in terms of these new
macros.

The OCMEM driver handles allocation and configuration of the On Chip
MEMory that is present on some Snapdragon SoCs. Devices which have
OCMEM do not have GMEM inside the GPU core, so the GPU must instead
use OCMEM to be functional. Since the GPU is currently the only OCMEM
user with an upstream driver, this is just a minimal implementation
sufficient for statically allocating to the GPU it's chunk of OCMEM.
This driver currently does not read the gmu-sram node that is described
in the device tree bindings. The starting memory address of the GPU's
reserved memory region is hardcoded to zero to match what the hardware
expects. The driver can be updated to read the reserved memory regions
from device tree once other users of OCMEM are added upstream.

driver subsystem trees are ending up in here. Now if that is good or
bad I can't tell, but hopefully it makes your life easier as it's more
of an aggregation of trees together to one merge point for you.
Anyway, lots of stuff in here:
- habanalabs driver updates
- thunderbolt driver updates
- misc driver updates
- coresight and intel_th hwtracing driver updates
- fpga driver updates
- extcon driver updates
- some dma driver updates
- char driver updates
- android binder driver updates
- nvmem driver updates
- phy driver updates
- parport driver fixes
- pcmcia driver fix
- uio driver updates
- w1 driver updates
- configfs fixes
- other assorted driver updates
All of these have been in linux-next for a long time with no reported
issues.

Here are the interconnect driver updates for the 5.4-rc1 merge window.
- New feature is the path tagging support that helps with grouping and
aggregating the bandwidth requests into separate buckets based on a tag.
- The first user of the path tagging is the Qualcomm sdm845 driver that
now implements support for wake/sleep sets. This allows consumer drivers
to express their bandwidth needs for the different CPU power states.
- New interconnect driver for the qcs404 platforms and a driver that
communicates bandwidth requests with remote processor over shared memory.
- Cleanups and fixes.

The "mediatek,larb-id" has already been parsed in MTK IOMMU driver.
It's no need to parse it again in SMI driver. Only clean some codes.
This patch is fit for all the current mt2701, mt2712, mt7623, mt8173
and mt8183.
After this patch, the "mediatek,larb-id" only be needed for mt2712
which have 2 M4Us. In the other SoCs, we can get the larb-id from M4U
in which the larbs in the "mediatek,larbs" always are ordered.
Correspondingly, the larb_nr in the "struct mtk_smi_iommu" could also
be deleted.

arc: prefer __section from compiler_attributes.h

This adds support for an optional extra interrupt cell to specify edge
vs level triggered. It is backward compatible with dts files with only
one cell, and will default to level-triggered in such a case.
Note that I had to make a change to idu_irq_set_affinity as well, as
this function was setting the interrupt type to "level" unconditionally,
since this was the only type supported previously.

Convert docs to ReST and add them to the arch-specific
book.
The conversion here was trivial, as almost every file there
was already using an elegant format close to ReST standard.
The changes were mostly to mark literal blocks and add a few
missing section title identifiers.
One note with regards to "--": on Sphinx, this can't be used
to identify a list, as it will format it badly. This can be
used, however, to identify a long hyphen - and "---" is an
even longer one.
At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

Add a couple of new APIs to check the probing status of the required
cpu bound qman and bman portals:
'int bman_portals_probed()' and 'int qman_portals_probed()'.
They return the following values.
* 1 if qman/bman portals were all probed correctly
* 0 if qman/bman portals were not yet probed
* -1 if probing of qman/bman portals failed
Portals are considered successful probed if no error occurred during
the probing of any of the portals and if enough portals were probed
to have one available for each cpu.
The error handling paths were slightly rearranged in order to fit this
new functionality without being too intrusive.
Drivers that use qman/bman portal driver services are required to use
these APIs before calling any functions exported by these drivers or
otherwise they will crash the kernel.
First user will be the dpaa1 ethernet driver, coming in a subsequent
patch.

this patch adds the functionality to do this. Also, if DDR clock
frequency is lower than the on-die termination (ODT) disable frequency
this driver should disable the DDR ODT.

dpaa2_io_service_register and the underlying dpaa2_io used. This link
will ensure that when a DPIO device, which is indirectly used by other
devices, is unbound any consumer devices will be also unbound from their
drivers.
For example, any DPNI, bound to the dpaa2-eth driver, which is using
DPIO devices will be unbound before its supplier device.
Also, add a new parameter to the dpaa2_io_service_[de]register functions
to specify the requesting device (ie the consumer).

The current implementation of the dpio driver uses a static next_cpu
variable to keep track of the index of the next cpu available. This
approach does not handle well unbinding and binding dpio devices in a
random order. For example, unbinding a dpio and then binding it again
with the driver, will generate the below error:
$ echo dpio.5 > /sys/bus/fsl-mc/drivers/fsl_mc_dpio/unbind
$ echo dpio.5 > /sys/bus/fsl-mc/drivers/fsl_mc_dpio/bind
[ 103.946380] fsl_mc_dpio dpio.5: probe failed. Number of DPIOs exceeds
NR_CPUS.
[ 103.955157] fsl_mc_dpio dpio.5: fsl_mc_driver_probe failed: -34
-bash: echo: write error: No such device
Fix this error by keeping a global cpumask of unused cpus that will be
updated at every dpaa2_dpio_[probe,remove].

Pull networking updates from David Miller:
1) New ipset extensions for matching on destination MAC addresses, from
Stefano Brivio.

nfp driver. From Stefano Brivio.
3) Implement GRO for plain UDP sockets, from Paolo Abeni.
4) Lots of work from Michał Mirosław to eliminate the VLAN_TAG_PRESENT
bit so that we could support the entire vlan_tci value.
5) Rework the IPSEC policy lookups to better optimize more usecases,
from Florian Westphal.
6) Infrastructure changes eliminating direct manipulation of SKB lists
wherever possible, and to always use the appropriate SKB list
helpers. This work is still ongoing...
7) Lots of PHY driver and state machine improvements and
simplifications, from Heiner Kallweit.
8) Various TSO deferral refinements, from Eric Dumazet.
9) Add ntuple filter support to aquantia driver, from Dmitry Bogdanov.

completely from the tree as it no longer has any users. From Oz
Shlomo and others.
22) Add a NETDEV_PRE_CHANGEADDR so that drivers can veto the change and
therefore abort the operation before the commit phase (which is the
NETDEV_CHANGEADDR event). From Petr Machata.

in the GRO code paths. From Paolo Abeni.
24) Add support for netlink FDB get operations, from Roopa Prabhu.
25) Support bloom filter in mlxsw driver, from Nir Dotan.
26) Add SKB extension infrastructure. This consolidates the handling of
