In preparation of the support for v4.20 PCIe PHY in SDX55, use a
separate "phy_status" field for the status bit offset. This is needed
because, the v4.20 PHY uses a different offset for the PHY Status.

For a single PHY, there's no reason to have a phy-names entry in DT.
The DT specific get functions allow for this already, but devm_phy_get()
WARNs in this case. Other subsystems also don't warn in their get
functions. Let's drop the WARN for DT case in devm_phy_get().

While IS_ENABLED() is perfectly fine for CONFIG_* symbols, it is not
for other symbols such as __BIG_ENDIAN that is provided directly by
the compiler.
Switch to use CONFIG_CPU_BIG_ENDIAN instead of __BIG_ENDIAN.

The way of printing the pointer address for the 'port_base'
address got into compile warnings on some architectures
[-Wpointer-to-int-cast]. Instead of use '%08x' and cast
to an 'unsigned int' just make use of '%px' and avoid the
cast. To avoid not really needed driver verbosity on normal
behaviour change also from 'dev_info' to 'dev_dbg'.

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)

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

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.

The Torrent spec specifies delay of 660.5us after phy_reset is
asserted by the controller. To be on the safe side provide a delay
of 5ms to 10ms in ->phy_on() callback where the SERDES is already
configured in bootloader.

Serdes lanes might be shared between multiple cores in some usecases
and its not possible to lock PLLs for both the lanes independently
by the two cores. This requires a bootloader to configure both the
lanes at early boot time.
To handle this case, skip all configuration if any of the lanes has
already been enabled.

or it can have sub-nodes for representing the various clocks within the

assigning "lane_phy_type", read only if the child node's name is "phy"

Ideally all PHY dt nodes should have node name as "phy", however
existing devicetree used "link" as subnode. So in order to maintain old
DT compatibility get PHY properties for "phy" or "link" subnode.

Add support for the USB DP & UNI PHYs found on SM8350. These use
version 5.0.0 of the QMP PHY IP and thus require new "V5"

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.

PLL block requires to be powered with 1v1 and 1v8 supplies to catch
ENABLE signal.
Currently, supplies are managed through phy_ops .power_on/off, and PLL
activation/deactivation is managed through phy_ops .init/exit.
The sequence of phy_ops .power_on/.phy_init, .power_off/.exit is USB
drivers dependent.
To ensure a good behavior of the PLL, supplies have to be managed at PLL
activation/deactivation. That means the supplies need to be put in usbphyc
node and not in phy children nodes.

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.

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.
