Bjorn Andersson bfccd9a71a phy: qcom-qmp: Fix sc8180x PCIe definition
A copy paste error was snuck into the patch going upstream that made the
SC8180x PCIe PHY use the SM8250 serdes table, but while this works
there's some differences in the tables (and the SC8180x was left
dangling). So correct the SC8180x definition to use the SC8180x serdes
table.

Chanho Park d64519249e phy: samsung-ufs: support exynosauto ufs phy driver
This patch adds to support phy-exynosautov9-ufs driver for ExynosAuto v9
series SoCs. The patch adds "samsung,exynosautov9-ufs-phy" compatible.
Unlike previous exynos ufs phy, the chip uses 0x50 offset as
PHY_TRSV_REG_CFG_OFFSET.

 Loads of IIO driver updates and additions in here, the shortlog has the

 For the staging side, we moved a few drivers out of staging, and deleted
 the kpc2000 drivers as the original developer asked us to because no one
 was working on them anymore.
 
 Also in here are loads of coding style cleanups due to different intern
 projects focusing on the staging tree to try to get experience doing
 kernel development.
 
 All of these have been in the linux-next tree for a while with no

The current driver uses a value from register TEST_O as the original

so there is a bug that the original value isn't no longer used.

The value of TEST_O[7:0] should be masked with "mask", replaced with
"param", and placed in the bitfield TESTI_DAT_MASK as new TEST_I value.

Aswath Govindraju a4a86d273f phy: phy-can-transceiver: Add support for generic CAN transceiver driver
The driver adds support for generic CAN transceivers. Currently
the modes supported by this driver are standby and normal modes for TI
TCAN1042 and TCAN1043 CAN transceivers.

The transceiver is modelled as a phy with pins controlled by gpios, to put
the transceiver in various device functional modes. It also gets the phy
attribute max_link_rate for the usage of CAN drivers.

To support XUSB host controller ELPG, this commit moves VBUS control
.phy_power_on()/.phy_power_off() to .phy_init()/.phy_exit().
When XUSB host controller enters ELPG, host driver invokes
.phy_power_off(), VBUS should remain ON so that USB devices will not
disconnect. VBUS can be turned OFF when host driver invokes
.phy_exit() which indicates disabling a USB port.

JC Kuo c545a90567 phy: tegra: xusb: Add sleepwalk and suspend/resume
This commit adds sleepwalk/wake and suspend/resume interfaces
to Tegra XUSB PHY driver.

Tegra XUSB host controller driver makes use of sleepwalk functions
to enable/disable sleepwalk circuit which is in always-on partition
and can respond to USB resume signals when controller is not powered.
Sleepwalk can be enabled/disabled for any USB UPHY individually.

  - tegra_xusb_padctl_enable_phy_sleepwalk()
  - tegra_xusb_padctl_disable_phy_sleepwalk()

Tegra XUSB host controller driver makes use of wake functions to
enable/disable/query wake circuit which is in always-on partition
can wake system up when USB resume happens.
Wake circuit can be enabled/disabled for any USB PHY individually.

  - tegra_xusb_padctl_enable_phy_wake()
  - tegra_xusb_padctl_disable_phy_wake()
  - tegra_xusb_padctl_remote_wake_detected()

This commit also adds two system suspend stubs that can be used to
save and restore XUSB PADCTL context during system suspend and
resume.
  - tegra_xusb_padctl_suspend_noirq()
  - tegra_xusb_padctl_resume_noirq()

JC Kuo 2352fdb0d3 phy: tegra: xusb: Rearrange UPHY init on Tegra210
This commit is a preparation for enabling XUSB SC7 support.
It rearranges Tegra210 XUSB PADCTL UPHY initialization sequence,
for the following reasons:

1. PLLE hardware power sequencer has to be enabled only after both
   PEX UPHY PLL and SATA UPHY PLL are initialized.
   tegra210_uphy_init() -> tegra210_pex_uphy_enable()
                        -> tegra210_sata_uphy_enable()
                        -> tegra210_plle_hw_sequence_start()
                        -> tegra210_aux_mux_lp0_clamp_disable()

2. At cold boot and SC7 exit, the following bits must be cleared after
   PEX/SATA lanes are out of IDDQ (IDDQ_DISABLE=1).
   a. XUSB_PADCTL_ELPG_PROGRAM1_AUX_MUX_LP0_CLAMP_EN,
   b. XUSB_PADCTL_ELPG_PROGRAM1_AUX_MUX_LP0_CLAMP_EN_EARLY
   c. XUSB_PADCTL_ELPG_PROGRAM1_AUX_MUX_LP0_VCORE_DOWN

   tegra210_pex_uphy_enable() and tegra210_sata_uphy_enable() are in
   charge of bringing lanes out of IDDQ, and then AUX_MUX_LP0_* bits
   will be cleared by tegra210_aux_mux_lp0_clamp_disable().

3. Once UPHY PLL hardware power sequencer is enabled, do not assert
   reset to PEX/SATA PLLs, otherwise UPHY PLL operation will be broken.

The programming sequence in tegra210_usb3_port_enable() is required
for both cold boot and SC7 exit, and must be performed only after
PEX/SATA UPHY is initialized. Therefore, this commit moves the
programming sequence to tegra210_usb3_phy_power_on(). PCIE/SATA phy
.power_on() stub will invoke tegra210_usb3_phy_power_on() if the lane
is assigned for XUSB super-speed.

Linus Torvalds 9d31d23389 Networking changes for 5.13.
Core:
 
  - bpf:
 	- allow bpf programs calling kernel functions (initially to
 	  reuse TCP congestion control implementations)
 	- enable task local storage for tracing programs - remove the
 	  need to store per-task state in hash maps, and allow tracing
 	  programs access to task local storage previously added for
 	  BPF_LSM
 	- add bpf_for_each_map_elem() helper, allowing programs to
 	  walk all map elements in a more robust and easier to verify
 	  fashion
 	- sockmap: support UDP and cross-protocol BPF_SK_SKB_VERDICT
 	  redirection
 	- lpm: add support for batched ops in LPM trie
 	- add BTF_KIND_FLOAT support - mostly to allow use of BTF
 	  on s390 which has floats in its headers files
 	- improve BPF syscall documentation and extend the use of kdoc
 	  parsing scripts we already employ for bpf-helpers
 	- libbpf, bpftool: support static linking of BPF ELF files
 	- improve support for encapsulation of L2 packets
 
  - xdp: restructure redirect actions to avoid a runtime lookup,
 	improving performance by 4-8% in microbenchmarks
 
  - xsk: build skb by page (aka generic zerocopy xmit) - improve
 	performance of software AF_XDP path by 33% for devices
 	which don't need headers in the linear skb part (e.g. virtio)
 
  - nexthop: resilient next-hop groups - improve path stability
 	on next-hops group changes (incl. offload for mlxsw)
 
  - ipv6: segment routing: add support for IPv4 decapsulation
 
  - icmp: add support for RFC 8335 extended PROBE messages
 
  - inet: use bigger hash table for IP ID generation
 
  - tcp: deal better with delayed TX completions - make sure we don't
 	give up on fast TCP retransmissions only because driver is
 	slow in reporting that it completed transmitting the original
 
  - tcp: reorder tcp_congestion_ops for better cache locality
 
  - mptcp:
 	- add sockopt support for common TCP options
 	- add support for common TCP msg flags
 	- include multiple address ids in RM_ADDR
 	- add reset option support for resetting one subflow
 
  - udp: GRO L4 improvements - improve 'forward' / 'frag_list'
 	co-existence with UDP tunnel GRO, allowing the first to take
 	place correctly	even for encapsulated UDP traffic
 
  - micro-optimize dev_gro_receive() and flow dissection, avoid
 	retpoline overhead on VLAN and TEB GRO
 
  - use less memory for sysctls, add a new sysctl type, to allow using
 	u8 instead of "int" and "long" and shrink networking sysctls
 
  - veth: allow GRO without XDP - this allows aggregating UDP
 	packets before handing them off to routing, bridge, OvS, etc.
 
  - allow specifing ifindex when device is moved to another namespace
 
  - netfilter:
 	- nft_socket: add support for cgroupsv2
 	- nftables: add catch-all set element - special element used
 	  to define a default action in case normal lookup missed
 	- use net_generic infra in many modules to avoid allocating
 	  per-ns memory unnecessarily
 
  - xps: improve the xps handling to avoid potential out-of-bound
 	accesses and use-after-free when XPS change race with other
 	re-configuration under traffic
 
  - add a config knob to turn off per-cpu netdev refcnt to catch
 	underflows in testing
 
 Device APIs:
 
  - add WWAN subsystem to organize the WWAN interfaces better and
    hopefully start driving towards more unified and vendor-
    -independent APIs
 
  - ethtool:
 	- add interface for reading IEEE MIB stats (incl. mlx5 and
 	  bnxt support)
 	- allow network drivers to dump arbitrary SFP EEPROM data,
 	  current offset+length API was a poor fit for modern SFP
 	  which define EEPROM in terms of pages (incl. mlx5 support)
 
  - act_police, flow_offload: add support for packet-per-second
 	policing (incl. offload for nfp)
 
  - psample: add additional metadata attributes like transit delay
 	for packets sampled from switch HW (and corresponding egress
 	and policy-based sampling in the mlxsw driver)
 
  - dsa: improve support for sandwiched LAGs with bridge and DSA
 
  - netfilter:
 	- flowtable: use direct xmit in topologies with IP
 	  forwarding, bridging, vlans etc.
 	- nftables: counter hardware offload support
 
  - Bluetooth:
 	- improvements for firmware download w/ Intel devices
 	- add support for reading AOSP vendor capabilities
 	- add support for virtio transport driver
 
  - mac80211:
 	- allow concurrent monitor iface and ethernet rx decap
 	- set priority and queue mapping for injected frames
 
  - phy: add support for Clause-45 PHY Loopback
 
  - pci/iov: add sysfs MSI-X vector assignment interface
 	to distribute MSI-X resources to VFs (incl. mlx5 support)
 
 New hardware/drivers:
 
  - dsa: mv88e6xxx: add support for Marvell mv88e6393x -
 	11-port Ethernet switch with 8x 1-Gigabit Ethernet
 	and 3x 10-Gigabit interfaces.

 	  queues with the stack when necessary
 
  - mlx5:
 	- flow rules: add support for mirroring with conntrack,
 	  matching on ICMP, GTP, flex filters and more
 	- support packet sampling with flow offloads
 	- persist uplink representor netdev across eswitch mode
 	  changes
 	- allow coexistence of CQE compression and HW time-stamping

Yang Yingliang e1723d8b87 phy: phy-twl4030-usb: Fix possible use-after-free in twl4030_usb_remove()
This driver's remove path calls cancel_delayed_work(). However, that
function does not wait until the work function finishes. This means
that the callback function may still be running after the driver's
remove function has finished, which would result in a use-after-free.

Fix by calling cancel_delayed_work_sync(), which ensures that
the work is properly cancelled, no longer running, and unable
to re-schedule itself.

Kishon Vijay Abraham I 9e405f87b6 phy: ti: j721e-wiz: Enable reference clock output in cmn_refclk_<p/m>
cmn_refclk_<p/m> lines in Torrent SERDES is used for connecting external
reference clock. cmn_refclk_<p/m> can also be configured to output the
reference clock. In order to drive the refclk out from the SERDES
(Cadence Torrent), PHY_EN_REFCLK should be set in SERDES_RST of WIZ.
Model PHY_EN_REFCLK as a clock, so that platforms like AM642 EVM can
enable it.

Kishon Vijay Abraham I 040cbe7687 phy: ti: j721e-wiz: Model the internal clocks without device tree input
commit 091876cc35 ("phy: ti: j721e-wiz: Add support for WIZ module
present in TI J721E SoC") modeled the internal clocks depending on the
subnodes that are populated in device tree. However recent discussions
in the mailing list [1] suggested to just add #clock cells in the parent
DT node and model the clocks within the driver.

Model the mux clocks without device tree input for AM64x SoC. Don't
remove the earlier design since DT nodes for J7200 and J721e are already
upstreamed.

Kishon Vijay Abraham I 549cb1ae3e phy: ti: j721e-wiz: Remove "regmap_field" from wiz_clk_{mux|div}_sel
Both "struct wiz_clk_div_sel" and "struct wiz_clk_mux_sel" are static
data that is common for all wiz instances. Including
"struct regmap_field" for each of the wiz instances can yield undesirable
results. Move "struct regmap_field" out of "struct wiz_clk_div_sel" and
"struct wiz_clk_mux_sel" and make them point to constant data.

So far no issues are observed since both these structures are not
accessed outside the probe.

Add support for Marvell CP110 UTMI PHY driver allowing the USB2
port configuration independently from the boot loader setup.
The CP110/CP115 dies have 2 UTMI PHYs that could be connected
to two USB host controllers or to single USB device controller.
Since there is only one USB device controller on die, only one
of the UTMI PHYs could work in USB device mode.
The CONFIG_PHY_MVEBU_CP110_UTMI should be enabled for usage of
this driver.

Amelie Delaunay 5b1af71280 phy: stm32: rework PLL Lock detection
USBPHYC has a register per phy to control and monitor the debug interface
of the HS PHY through a digital debug access.
With this register, it is possible to know if PLL Lock input to phy is
high. That means the PLL is ready for HS operation.
Instead of using an hard-coded delay after PLL enable and PLL disable, use
this bit to ensure good operating of the HS PHY.
Also use an atomic counter (n_pll_cons) to count the actual number of PLL
consumers and get rid of stm32_usbphyc_has_one_phy_active.
The boolean active in the usbphyc_phy structure is kept, because we need to
know in remove if a phy_exit is required to properly disable the PLL.

Colin Ian King b097efba95 drm/mediatek: avoid dereferencing a null hdmi_phy on an error message
Currently there is a null pointer check for hdmi_phy that implies it
may be null, however a dev_err messages dereferences this potential null
pointer.  Avoid a null pointer dereference by only emitting the dev_err
message if hdmi_phy is non-null.  It is a moot point if the error message
needs to be printed at all, but since this is a relatively new piece of
code it may be useful to keep the message in for the moment in case there
are unforseen errors that need to be reported.

This driver includes the following two files directly:
- mt7621.h
- ralink_regs.h

Compilation for its related platform properly works because
its real path is included in 'arch/mips/ralink/Platform' as
cflags.

This driver depends on RALINK but also is enabled for COMPILE_TEST
where nothing about its platform is known and this directly
included files are not found at all breaking compilation.

If we want 'COMPILE_TEST' we have to change cflags also inside
'phy/ralink' subdirectory Makefile which seems that does not
like to linux-phy maintainers. Hence remove COMPILE_TEST from
Kconfig to avoid the problem.

JC Kuo 4ea0bf2a52 phy: tegra: xusb: Fix usb_phy device driver field
In commit "phy: tegra: xusb: Add usb-phy support", an OTG capable PHY
device, such as phy-usb2.0 device of Jetson-TX1 platform, will be
bound to the tegra-xusb-padctl driver by the following line in
tegra_xusb_setup_usb_role_switch().

	port->usb_phy.dev->driver = port->padctl->dev->driver;

With this, dev_pm_ops set of tegra-xusb-padctl driver will be invoked
for the OTG capable PHY incorrectly as below logs show.

This commit fixes the issue by assigning an empty driver to it.

Initially this PHY driver was implementing MDIO access on its own. It
was caused by lack of proper hardware design understanding.

It has been changed back in 2017. DT bindings were changed and driver
was updated to use MDIO layer.

It should be really safe now to drop the old deprecated code. All Linux
stored DT files don't use it for 3,5 year. There is close to 0 chance
there is any bootloader with its own DTB using old the binding.

SM8250 has multiple different PHY versions:
QMP GEN3x1 PHY - 1 lane
QMP GEN3x2 PHY - 2 lanes
QMP Modem PHY - 2 lanes

Add support for these with relevant init sequence. In order to abstract
the init sequence, this commit introduces secondary tables which can
be used to factor out the unique sequence for each PHY while the former
tables can have the common sequence.

Marc Zyngier eb9c4dd9bd phy: tegra: xusb: Fix dangling pointer on probe failure
If, for some reason, the xusb PHY fails to probe, it leaves
a dangling pointer attached to the platform device structure.

This would normally be harmless, but the Tegra XHCI driver then
goes and extract that pointer from the PHY device. Things go
downhill from there:

Al Cooper 209c805835 phy: usb: Fix incorrect clearing of tca_drv_sel bit in SETUP reg for 7211
The 7211a0 has a tca_drv_sel bit in the USB SETUP register that
should never be enabled. This feature is only used if there is a
USB Type-C PHY, and the 7211 does not have one. If the bit is
enabled, the VBUS signal will never be asserted. In the 7211a0,
the bit was incorrectly defaulted to on so the driver had to clear
the bit. In the 7211c0 the state was inverted so the driver should
no longer clear the bit. This hasn't been a problem because all
current 7211 boards don't use the VBUS signal, but there are some
future customer boards that may use it.

Pull drm updates from Dave Airlie:
 "Not a major amount of change, the i915 trees got split into display
  and gt trees to better facilitate higher level review, and there's a
  major refactoring of i915 GEM locking to use more core kernel concepts
  (like ww-mutexes). msm gets per-process pagetables, older AMD SI cards
  get DC support, nouveau got a bump in displayport support with common
  code extraction from i915.

  Outside of drm this contains a couple of patches for hexint
  moduleparams which you've acked, and a virtio common code tree that
  you should also get via it's regular path.

Pali Rohár ea17a0f153 phy: marvell: comphy: Convert internal SMCC firmware return codes to errno
Driver ->power_on and ->power_off callbacks leaks internal SMCC firmware
return codes to phy caller. This patch converts SMCC error codes to
standard linux errno codes. Include file linux/arm-smccc.h already provides
defines for SMCC error codes, so use them instead of custom driver defines.
Note that return value is signed 32bit, but stored in unsigned long type
with zero padding.

This is a warning but not a practical one as dp_cfg, dp_serdes and
usb_cfg will be set and used when valid. So we can set the pointers to
NULL to quiesce the warnings.

Stephen Boyd 52e013d0bf phy: qcom-qmp: Add support for DP in USB3+DP combo phy
Add support for the USB3 + DisplayPort (DP) "combo" phy to the qmp phy
driver. We already have support for the USB3 part of the combo phy, so
most additions are for the DP phy.

Split up the qcom_qmp_phy{enable,disable}() functions into the phy init,
power on, power off, and exit functions that the common phy framework
expects so that the DP phy can add even more phy ops like
phy_calibrate() and phy_configure(). This allows us to initialize the DP
PHY and configure the AUX channel before powering on the PHY at the link
rate that was negotiated during link training.

The general design is as follows:

  1) DP controller calls phy_init() to initialize the PHY and configure
  the dp_com register region.

  2) DP controller calls phy_configure() to tune the link rate and
  voltage swing and pre-emphasis settings.

  3) DP controller calls phy_power_on() to enable the PLL and power on
  the phy.

  4) DP controller calls phy_configure() again to tune the voltage swing
  and pre-emphasis settings determind during link training.

  5) DP controller calls phy_calibrate() some number of times to change
  the aux settings if the aux channel times out during link training.

  6) DP controller calls phy_power_off() if the link rate is to be
  changed and goes back to step 2 to try again at a different link rate.

  5) DP controller calls phy_power_off() and then phy_exit() to power
  down the PHY when it is done.

The DP PHY contains a PLL that is different from the one used for the
USB3 PHY. Instead of a pipe clk there is a link clk and a pixel clk
output from the DP PLL after going through various dividers. Introduce
clk ops for these two clks that just tell the child clks what the
frequency of the pixel and link are. When the phy link rate is
configured we call clk_set_rate() to update the child clks in the
display clk controller on what rate is in use. The clk frequencies
always differ based on the link rate (i.e. 1.6Gb/s 2.7Gb/s, 5.4Gb/s, or
8.1Gb/s corresponding to various transmission modes like HBR1, HBR2 or
HBR3) so we simply store the link rate and use that to calculate the clk
frequencies.

The PLL enable sequence is a little different from other QMP phy PLLs so
we power on the PLL in qcom_qmp_phy_configure_dp_phy() that gets called
from phy_power_on(). This should probably be split out better so that
each phy has a way to run the final PLL/PHY enable sequence.

This code is based on a submission of this phy and PLL in the drm
subsystem.

Stephen Boyd aa968cb1a6 phy: qcom-qmp: Move 'serdes' and 'cfg' into 'struct qcom_phy'
The serdes I/O region is where the PLL for the phy is controlled.
Sometimes the PLL is shared between multiple phys, for example in the
PCIe case where there are three phys inside the same wrapper. Other
times the PLL is for a single phy, i.e. some USB3 phys. To complete the
trifecta we have the USB3+DP combo phy where the USB3 and DP phys each
have their own serdes region because they have their own PLL while they
both share a common I/O region pertaining to the USB type-c pinout and
cable orientation.

Let's move the serdes iomem pointer into 'struct qmp_phy' so that we can
correlate PLL control to the phy that uses it. This allows us to support
the USB3+DP combo phy in this driver. This isn't a problem for the
3-lane/phy PCIe phy because there is a common init function that is the
only place the serdes region is programmed.

Furthermore, move the configuration data that contains most of the
register programming sequences to the qmp phy struct. This data isn't
qmp wrapper specific. It is phy specific data used to tune various
settings for things like pre-emphasis, bias, etc.

wrapper wide data is located, paving the way for the USB3+DP combo phy.
