[PATCH v7 phy-next 01/27] ata: add <linux/pm_runtime.h> where missing

[Vladimir Oltean]

It appears that libahci.c, ahci.c as well as the ahci_brcm, ahci_ceva
and ahci_qoriq drivers are using runtime PM operations without including
<linux/pm_runtime.h>. This header is somehow being indirectly provided
by <linux/phy/phy.h>, which would like to drop it (none of the functions
it exports need it).

[PATCH v7 phy-next 02/27] PCI: Add missing headers transitively included by <linux/phy/phy.h>

[Vladimir Oltean]

The tegra as well as a few dwc PCI controller drivers uses PM runtime
operations without including the required <linux/pm_runtime.h> header.

Similarly, pcie-rockchip-host, pcie-starfive as well as a few dwc PCI
controllers use the regulator consumer API without including
<linux/regulator/consumer.h>.

pcie-spacemit-k1.c uses of_get_next_available_child() and of_node_put()
without including <linux/of.h>.

It seems these function prototypes were indirectly provided by
<linux/phy/phy.h>, mostly by mistake (none of the functions it exports
need it).

Before the PHY header can drop the unnecessary includes, make sure the
PCI controller drivers include what they use.

[PATCH v7 phy-next 03/27] usb: add missing headers transitively included by <linux/phy/phy.h>

[Vladimir Oltean]

The chipidea ci_hdrc_imx driver uses regulator consumer API like
regulator_enable() but does not include <linux/regulator/consumer.h>.

The core USB HCD driver calls invalidate_kernel_vmap_range() and
flush_kernel_vmap_range(), but does not include <linux/highmem.h>.

The DWC3 gadget driver calls:
- device_property_present()
- device_property_count_u8()
- device_property_read_u8_array()
but does not include <linux/property.h>

Similarly, dwc3-imx uses device_property_read_bool() without including
<linux/property.h>.

The dwc3-generic-plat driver uses of_device_get_match_data() but does
not include <linux/of.h>.

In all these cases, the necessary includes were still provided somehow,
directly or indirectly, through <linux/phy/phy.h>. I found the following
command to be quite helpful in figuring out the include chain:

$ make KCFLAGS="-H" drivers/usb/dwc3/dwc3-imx.o

Since <linux/phy/phy.h> wants to drop the unnecessary includes, fill in
the required headers to avoid any breakage.

[PATCH v7 phy-next 04/27] drm: add <linux/pm_runtime.h> where missing

[Vladimir Oltean]

Multiple DRM bridge drivers use runtime PM operations without
including the proper header, instead relying on transitive inclusion
by <linux/phy/phy.h>.

The PHY subsystem wants to get rid of headers it provides for no reason,
so modify these drivers to include what they need directly.

[PATCH v7 phy-next 05/27] phy: add <linux/pm_runtime.h> where missing

[Vladimir Oltean]

It appears that the phy-mapphone-mdm6600, phy-qcom-snps-femto-v2,
phy-rcar-gen3-pcie, r8a779f0-ether-serdes and phy-rockchip-typec drivers
call runtime PM operations without including the proper header.

This was provided by <linux/phy/phy.h> but no function exported by this
header directly needs it. So we need to drop it from there, and fix up
drivers that used to depend on that.

[PATCH v7 phy-next 07/27] net: lan969x: include missing <linux/of.h>

[Vladimir Oltean]

This file is calling of_property_read_u32() without including the proper
header for it. It is provided by <linux/phy/phy.h>, which wants to get
rid of it.

[PATCH v7 phy-next 08/27] PCI: Remove device links to PHY

[Vladimir Oltean]

This is practically a full revert of commit
7a4db656a635 ("PCI: dra7xx: Create functional dependency between PCIe and PHY")
and a partial revert of the device link pieces from commits
dfb80534692d ("PCI: cadence: Add generic PHY support to host and EP drivers")
49229238ab47 ("PCI: keystone: Cleanup PHY handling")

The trouble with these commits is that they dereference fields inside
struct phy from a consumer driver, which will become no longer possible.

Since commit 987351e1ea77 ("phy: core: Add consumer device link
support") from 2019, the PHY core also adds a device link to order PHY
provider and consumer suspend/resume operations. All reverted commits
are from 2017-2018, and what they do should actually be redundant now.

The condition does not appear intentional. Commit bd22885aa188 ("PCI:
cadence: Refactor driver to use as a core library") changed
cdns_pcie_host_probe() which properly returned ret on error with
cdns_plat_pcie_probe() which doesn't.

I will add a preparatory patch which replaces "return 0" with "return ret"
in cdns_plat_pcie_probe(), blaming that commit.

It seems plausible that the pm_runtime_put() -> pm_runtime_disable()
pattern is ineffective, i.e. one of two things can happen: either
pm_runtime_put() runs to completion by chance, or pm_runtime_disable()
cancels it. However I am not very familiar with the runtime PM API and
its effects, and unless a maintainer tells me to, I would prefer leaving
these code paths alone.

[PATCH v7 phy-next 09/27] scsi: ufs: exynos: stop poking into struct phy guts

[Vladimir Oltean]

The Exynos host controller driver is clearly a PHY consumer (gets the
ufs->phy using devm_phy_get()), but pokes into the guts of struct phy
to get the generic_phy->power_count.

The UFS core (specifically ufshcd_link_startup()) may call the variant
operation exynos_ufs_pre_link() -> exynos_ufs_phy_init() multiple times
if the link startup fails and needs to be retried.

However ufs-exynos shouldn't be doing what it's doing, i.e. looking at
the generic_phy->power_count, because in the general sense of the API, a
single Generic PHY may have multiple consumers. If ufs-exynos looks at
generic_phy->power_count, there's no guarantee that this ufs-exynos
instance is the one who previously bumped that power count. So it may be
powering down the PHY on behalf of another consumer.

The correct way in which this should be handled is ufs-exynos should
*remember* whether it has initialized and powered up the PHY before, and
power it down during link retries. Not rely on the power_count (which,
btw, on the writer side is modified under &phy->mutex, but on the reader
side is accessed unlocked). This is a discouraged pattern even if here
it doesn't cause functional problems.

I think I've been looking at this issue all wrong, not considering why
the UFS HCD driver calls phy_exit() -> phy_init() at runtime and what
can be done about that.

I have replaced this patch with the one attached, which I will be sending
for v8.

Subject: [PATCH] scsi: ufs: exynos: use dedicated API for updating PHY bus
 width

I am trying to get rid of code instances where PHY consumers (like the
Exynos UFS HCD) poke inside struct phy fields, in order to further turn
struct phy into an opaque data structure.

The ufs-exynos.c driver interacts with phy-samsung-ufs.c in order to
power it on and to update the lane count. For the later purpose, it
(ab)uses phy_set_bus_width().

The phy_set_bus_width() function is a PHY provider function, not a
consumer one, and I am calling its use from ufs-exynos.c an abuse
because
(1) commit 8feed347d33b ("phy: add phy_get_bus_width()/phy_set_bus_width()
    calls") clearly states so.
(2) phy_set_bus_width() only alters phy->attrs.bus_width, and does not
    call into phy_ops at all. So a consumer that makes a call to
    phy_set_bus_width() will not produce any hardware change in the
    provider at all.

This is where the Exynos UFS HCD driver decided to be creative and
hijacked phy_init() to pick up the bus_width attribute.

This requires a very careful dance where the PHY consumer needs to
simultaneously juggle two requirements:
- the UFS PHY needs to pick up the updated lane count in its
  samsung_ufs_phy_init() handler for the phy_init() call
- phy_init() calls need to be balanced with phy_exit(), otherwise
  subsequent phy_init() calls don't make it into samsung_ufs_phy_init()
  and just leave the PHY with an elevated init_count
- phy_power_on() can't be called without phy_init()

This is why the following bug fix commits exist:
3d73b200f989 ("scsi: ufs: ufs-exynos: Change ufs phy control sequence")
7f05fd9a3b6f ("scsi: ufs: exynos: Ensure consistent phy reference counts")

Currently the UFS HCD driver tries to keep the PHY init_count and
power_count in tight lockstep, but even this is error-prone. For
example, if exynos_ufs_suspend() runs and then exynos_ufs_exit(),
the PHY power_count will underflow.

If we address the root issue first (phy_init() abused to pick up new
lane count) by introducing a new PHY consumer method which actually does
call into the PHY provider driver, then we are able to absorb the entire
UFS HCD dance and update the lane count without altering the PHY
init_count or power_count.

Then we are much more free to call phy_init() from wherever we want, and
same goes for phy_power_on().

It is typical to call phy_init() right after phy_get(), and doing so
will naturally balance it with phy_exit().

We can also leave the phy_power_on() call to be on demand, placed inside
exynos_ufs_pre_link(). Because this call can be made multiple times and
is not balanced with anything else, we need a consumer-specific "bool
phy_powered_on" which ensures that we call phy_power_on() at most once,
and that exynos_ufs_exit() only calls phy_power_off() if phy_power_on()
was previously called. Using the phy->power_count for this purpose is
undesirable because
(a) it is going away
(b) the PHY API supports multiple consumers for the same provider, so it
    cannot offer an equivalent helper because it doesn't want consumers
    to interfere with each other

Inside the new samsung_ufs_phy_request_bus_width(), I've sanity checked
that the bus width is either 1 or 2 lanes. This coincides with
samsung_ufs_phy_config() which only configures LANE_0 and LANE_1.

[PATCH v7 phy-next 10/27] scsi: ufs: qcom: keep parallel track of PHY power state

[Vladimir Oltean]

PHY consumer drivers should not look at the phy->power_count (a PHY
internal field), because in the general case there might also be other
consumers who have called phy_power_on() too, so the fact that the
power_count is non-zero does not mean that we did.

Moreover, struct phy will become opaque soon, so the qcom UFS driver
will not be able to apply this pattern anymore.

By all accounts, the need for ufs_qcom_power_up_sequence() to call
phy_power_off() prior to phy_init() denotes a skewed state of affairs.

(1) The Generic PHY API warns if phy_power_on() is called prior to
    phy_init() - which ufs-qcom.c does, from ufs_qcom_setup_clocks().
    The UFS controller driver hides its tracks by dropping the power
    count prior to phy_init(), and that API violation goes undetected.

(2) phy_calibrate(), as implemented by the phy-qcom-qmp-ufs.c provider,
    only works once after power on. Next time it will time out. And
    since ufs_qcom_hce_enable_notify() -> ufs_qcom_power_up_sequence()
    is called in a retry loop by the UFS core, the PHY power would
    normally be on, hence the phy_power_off() call to ensure the
    consistent state during phy_calibrate().

The above constitute improper Generic PHY API use, *but* fixing that
requires delicate surgery and I'm only here to stop this PHY consumer
from using fields it's not supposed to.

Once this discussion is settled, I will also address the above issues as
follow-ups:
https://lore.kernel.org/linux-phy/20260327112858.r5lpqygtvsane2vf@skbuf/

Until then, we can reimplement the logic in this driver in a
bug-compatible way, by keeping parallel track of just the UFS
controller's calls to phy_power_on() and phy_power_off().

Note that phy_power_off() shouldn't return an error in general and
doesn't return an error in the particular case of the phy-qcom-qmp-ufs.c
provider.  So I've removed the one handling of phy_power_off() errors
from ufs_qcom_setup_clocks().

[PATCH v7 phy-next 11/27] scsi: ufs: qcom: include missing <linux/interrupt.h>

[Vladimir Oltean]

This driver uses devm_request_irq() without including <linux/interrupt.h>
by itself, which would lead to build failures if the headers providing
this transitively were to stop providing it.

On aarch64, we can see, using KCFLAGS='-H' make drivers/ufs/host/ufs-qcom.o,
that the inclusion path is:
drivers/ufs/host/ufs-qcom.c
-> include/linux/acpi.h
   -> arch/arm64/include/asm/acpi.h
      -> include/linux/efi.h
         -> include/linux/rtc.h
            -> include/linux/interrupt.h

Whereas on armv7, the situation is quite different. This architecture
has no CONFIG_ACPI symbol, and therefore on it, <linux/acpi.h> does not
include <asm/acpi.h>, and <linux/interrupt.h> is not provided that way.

It is provided, however, through this "fallback" path:

drivers/ufs/host/ufs-qcom.c
-> include/linux/phy/phy.h
   -> include/linux/regulator/consumer.h
      -> include/linux/suspend.h
         -> include/linux/swap.h
            -> include/linux/memcontrol.h
               -> include/linux/writeback.h
                  -> include/linux/interrupt.h

The point is that <linux/phy/phy.h> will stop providing
<linux/regulator/consumer.h>, and this would break the transitive
include chain on armv7.

[PATCH v7 phy-next 12/27] drm/rockchip: dw_hdmi: avoid direct dereference of phy->dev.of_node

[Vladimir Oltean]

The dw_hdmi-rockchip driver validates pixel clock rates against the
HDMI PHY's internal clock provider on certain SoCs like RK3328.
This is currently achieved by dereferencing hdmi->phy->dev.of_node
to obtain the provider node, which violates the Generic PHY API's
encapsulation (the goal is for struct phy to be an opaque pointer
with a hidden definition, to be interacted with only using API
functions or NULL pointer checks, for the case where optional variants
of phy_get() did not find a PHY).

Refactor dw_hdmi_rockchip_bind() to perform a manual phandle lookup
on the "hdmi" PHY index within the controller's DT node. This provides
a parallel path to the clock provider's OF node without relying on the
internal structure of the struct phy handle.

[PATCH v7 phy-next 13/27] usb: host: tegra: avoid direct dereference of phy->dev.of_node

[Vladimir Oltean]

A piece of context which seems relevant here is that the USB subsystem
is transitioning from struct usb_phy to struct phy (belonging to the
Generic PHY subsystem). Commit 1a229d8690a0 ("Revert "usb: phy: add usb
phy notify port status API"") seems to confirm that this is the case.

In the transition process, some PHY provider drivers register themselves
as both Generic PHY and USB PHY in an attempt to bridge the API gap.
Such is the case with drivers/phy/tegra/xusb.c, accessed here by the
Tegra USB host driver. This USB host expects the PHY device behind the
Generic PHY to also be a USB PHY, and calls
devm_usb_get_phy_by_node(phy->dev.of_node).

The Generic PHY exposes no API to get the OF node from a PHY device, so
the Tegra USB host driver gets it directly. However, "struct phy" will
be made an opaque pointer, to avoid misuse, so this will no longer be
possible.

Considering the fact that the Generic PHY/USB PHY duality is a
transitional state, I am deliberately not planning to make the life of
this driver any easier by providing a helper to get to the OF node
somehow. Instead, implement a parallel lookup path through which the
Tegra USB host driver can continue to get to the OF node provided by the
padctl component, using the 'phys' phandle.

Secondly (minor issue) the driver uses the phy->dev.of_node again to
print using dev_dbg() that a "remote wake" was detected. Just print the
index at which the PHY appears inside the driver's tegra->phys[] array
instead.

I've added an of_node_put(args.np) after devm_usb_get_phy_by_node() for v8.

If this is a problem, it is a pre-existing and completely unrelated

[PATCH v7 phy-next 14/27] usb: gadget: tegra-xudc: avoid direct dereference of phy->dev.of_node

[Vladimir Oltean]

In a somewhat similar situation as the Tegra USB host controller driver,
the Tegra XUDC driver for USB gadget mode needs to get to a struct
usb_phy that sits behind the same OF node as the Generic PHY. It does
that directly, which will no longer be possible. The PHY provider is
also the xusb padctl driver.

The rework here is also to implement a parallel OF node lookup path
based on the "phys" phandle and the #phy-cells of the padctl provider.

Some further notes:
- create a local "usbphy" variable to hold the devm_usb_get_phy_by_node()
  output. This makes the error checks more obvious (avoids keeping an
  error-encoded pointer in xudc->usbphy[i] even temporarily).
- the "if (IS_ERR(utmi_phy)) .. else if (utmi_phy) .. else if (!utmi_phy)"
  pattern can be simplified, considering that neither the IS_ERR() nor
  the NULL case continue execution in the current block. Therefore, we
  can move the case where the "utmi_phy" is a valid pointer outside the
  "if" checks, and this reduces the code indentation level.

This is correct, I've removed the duplicated "err" variable declaration

This is correct, although theoretically of_property_match_string() and
of_parse_phandle_with_args() should not fail as long as devm_phy_optional_get()
succeeded for that very same phy_name starting from the very same OF node.
But nonetheless, if this happens due to bugs, I've instead treated the
condition as fatal and printed error messages for v8.

[PATCH v7 phy-next 16/27] phy: make phy_get_mode(), phy_(get|set)_bus_width() NULL tolerant

[Vladimir Oltean]

The PHY API has an optional "get" which returns NULL, so it needs to
accept that NULL coming back in.

Most PHY functions do this, only the formerly static inline attribute
dereferences did not.

[PATCH v7 phy-next 17/27] phy: introduce phy_get_max_link_rate() helper for consumers

[Vladimir Oltean]

Consumer drivers shouldn't dereference struct phy, not even to get to
its attributes.

We have phy_get_bus_width() as a precedent for getting the bus_width
attribute, so let's add phy_get_max_link_rate() and use it in DRM and
CAN drivers.

In CAN drivers, the transceiver is acquired through devm_phy_optional_get()
and NULL is given by the API as a non-error case, so the PHY API should
also tolerate NULL coming back to it. This means we can further simplify
the call sites that test for the NULL quality of the transceiver.

Yeah... Let's see what other review comments pop up (including Sashiko,
which would be seeing this series for the first time) and decide
afterwards whether to make the argument const for the new getters as
part of a separate set, or in v8.

I don't think that modifying the existing getters is in scope for this
27 patch set.

[PATCH v7 phy-next 18/27] drm/rockchip: dsi: include PHY provider header

[Vladimir Oltean]

The Rockchip DSI controller is a PHY consumer driver, which is also a
PHY provider (calls devm_phy_create()) that lives out of drivers/phy/.

According to Vinod, this is discouraged, although it would be difficult
for me to address a proper movement here.

[PATCH v7 phy-next 19/27] drm: bridge: cdns-mhdp8546: use consumer API for getting PHY bus width

[Vladimir Oltean]

The Cadence MHDP8546 DP bridge driver gets the PHY bus_width attribute
(holding number of lanes) directly, but doing this will no longer be
possible after the definition of struct phy is hidden from consumers.

Use the phy_get_bus_width() API function designed specifically for
consumers.

[PATCH v7 phy-next 20/27] media: sunxi: a83-mips-csi2: include PHY provider header

[Vladimir Oltean]

The introduction commit 576d196c522b ("media: sunxi: Add support for the
A83T MIPI CSI-2 controller") says:

    This implementation splits the protocol and D-PHY registers and
    uses the PHY framework internally. The D-PHY is not registered as a
    standalone PHY driver since it cannot be used with any other
    controller.

However, this does not matter, and is not the only instance of tight PHY
provider <-> consumer pairing. According to Vinod Koul, having PHY
provider drivers outside of drivers/phy/ is discouraged, although it
would be difficult for me to address a proper movement here.

So just include the private provider API header from drivers/phy/ and
leave a FIXME in place.

[PATCH v7 phy-next 21/27] net: renesas: rswitch: include PHY provider header

[Vladimir Oltean]

As a PHY consumer driver, the Renesas rswitch dereferences internal
fields of struct phy, something which shouldn't be done, as that is
going to be made an opaque pointer.

It is quite clearly visible that the driver is tightly coupled with the
drivers/phy/renesas/r8a779f0-ether-serdes.c, which puts heavy pressure
on the Generic PHY subsystem.

This was discussed before here:
https://lore.kernel.org/linux-phy/20260211194541.cdmibrpfn6ej6e74@skbuf/

but to summarize, it is generally expected that when a Generic PHY
function is called, it takes effect immediately. When this doesn't
happen, the PHY provider driver must change its implementation rather
than the consumer be made to work around it. PHY providers which rely on
a hardcoded call sequence in the consumer are just lazy and wrong.

The most obvious example is commit 5cb630925b49 ("net: renesas: rswitch:
Add phy_power_{on,off}() calling"). Problem description:
- Ethernet PHYs may change phydev->interface. When this happens, the
  SerDes must learn of the new phydev->interface using phy_set_mode_ext().
- drivers/phy/renesas/r8a779f0-ether-serdes.c implements phy_set_mode_ext(),
  but this only caches the mode and submode into channel->phy_interface
  and applies this to hardware during phy_power_on().

The commit author decided to work around this at the consumer site, by
power cycling the PHY for the configuration to take effect.

This had a worse implication from an API perspective in subsequent
commit 053f13f67be6 ("rswitch: Fix imbalance phy_power_off() calling").
It was observed that phy_power_on() and phy_power_off() calls need to be
balanced, and so, the consumer decided to start looking at the struct
phy :: power_count (the technical reason why I'm making this change).

This is also wrong from an API perspective because
- a consumer should only care about its own vote on the PHY power state.
  If this is a multi-port submode like QSGMII, a single phy_power_off()
  call will not actually turn the PHY off (nor should it).
- the power_count is written under the &phy->mutex, but read unlocked
  here.

The rswitch and r8a779f0-ether-serdes drivers both need to be completely
rethought in terms of Generic PHY API call sequence. There is no quick
fix to apply. Just include the PHY provider API along with the consumer
one, to keep working as before when struct phy will be made an opaque
pointer to normal PHY consumers. But this is a bad offender (and it's
not even a provider) so add a FIXME.

I will ignore this comment. Inaction will leave the driver in exactly
the same state as before. Not great, true, but I don't see how not
changing anything could cause a regression.

[PATCH v7 phy-next 22/27] pinctrl: tegra-xusb: include PHY provider header

The tegra-xusb pinctrl driver is also a PHY provider (calls
devm_phy_create() for PCIe and SATA). However, according to Vinod Koul,
having PHY provider drivers outside of drivers/phy/ is discouraged,
although it would be difficult for me to address a proper movement here.

Include the private provider API header from drivers/phy/, but leave a

With the future removal of drivers/phy/phy-provider.h from

[PATCH v7 phy-next 24/27] phy: include PHY provider header (1/2)

[Vladimir Oltean]

The majority of PHY drivers are PHY providers (obviously).

Some are providers *and* consumers (phy-meson-axg-mipi-dphy,
phy-meson-axg-pcie). These are the Amlogic AXG SoCs, which split the
physical layer into two chained PHYs: the digital layer and the analog
layer. The DSI or PCIe controller interacts only with the digital PHY,
presumably for simplicity.

The rest of PHY drivers which include <linux/phy/phy.h> do so because
they call phy_set_bus_width(), a consumer function.

[PATCH v7 phy-next 25/27] phy: include PHY provider header (2/2)

[Vladimir Oltean]

The majority of PHY drivers are PHY providers (obviously).

Some are chained PHY provider+consumer (phy-qcom-m31-eusb2.c,
phy-exynos5-usbdrd.c).

Others include <linux/phy/phy.h> because they call consumer functions
such as phy_pm_runtime_get() - phy-mapphone-mdm6600.c. See commit
2ad2af081622 ("phy: mapphone-mdm6600: Improve phy related runtime PM
calls") for the story behind that. My understanding is it's a pragmatic
shortcut, but it doesn't bother much.

v6->v7:
- manually resolved conflict in
  drivers/phy/qualcomm/phy-qcom-sgmii-eth.c with commit 4ff5801f45b4
  ("phy: qcom-sgmii-eth: add .set_mode() and .validate() methods"), now
  present in linux-phy/next.
v4->v6: none
v3->v4:
- fix phy-provider.h path from drivers/phy/qualcomm/phy-qcom-ipq806x-sata.c
- make sure include/linux/phy/tegra/xusb.h is not reliant upon an
  external "struct phy" definition
v2->v3: none
v1->v2: split in two parts to pass through linux-phy mailing list
moderation. The split is at letter 'q' (Qualcomm)

The LLM review is right that the relative include path is wrong.

I have moved the file from include/linux/phy/ulpi_phy.h to drivers/phy/ulpi_phy.h
for v8, and updated the relative include path to just "phy-provider.h".
Frankly, it is an oversight that ulpi_phy.h was still left in the public
<linux/phy/> directory.

[PATCH v7 phy-next 27/27] MAINTAINERS: add regexes for linux-phy

[Vladimir Oltean]

Some pragmatic shortcuts are being taken by PHY consumer driver authors,
which put a burden on the framework. A lot of these can be caught during
review.

Make sure the linux-phy list is copied on as many keywords that regexes
can reasonably catch.

Some considerations that led to this solution and not a simpler one:
- Consumers may be located anywhere, and their file naming provides no
  indication whatsoever that they are PHY API consumers.
- The network PHY API has similarly sounding API: phy_start(),
  phy_connect(), etc. Similarly, matching on "phy" would hit
  phys_addr_t, "cryptography", etc.
- The header files themselves need attention to avoid matching on
  include/linux/phy.h (network PHY), include/linux/usb/phy.h,
  drivers/net/vendor/device/phy.h, etc.
- At least for a transitional period, I suppose developers will still
  try to add PHY providers outside the subsystem (which is discouraged).

So I used \b to try to match on actual word boundaries and I went for
listing all markers of PHY API use as they may appear in patch contexts.

Bit rot is a valid concern. I will add a test to the build automation
that newly introduced struct and function names in include/linux/phy.h,
include/linux/phy-props.h and drivers/phy/phy-provider.h are matched by
the MAINTAINERS entry K: patterns.

The keyword patterns were written with great help from Joe Perches
<joe@perches.com>.

v3->v7: none
v2->v3:
- escape forward slash in linux/phy/phy.h in regex pattern:
  https://lore.kernel.org/linux-phy/9fd14d166e860f26febfbc9061a6dcae6a166961.camel@perches.com/
v1->v2:
- split into multiple regex patterns
- use matching-only (insted of capturing) regex patterns
- adjust commit message to reflect the Q&A from v1
