[PATCH v5 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 v5 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 v5 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>

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>. The latter header
wants to drop those includes, so fill in the required headers to avoid
any breakage.

[PATCH v5 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 v5 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 v5 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.

[PATCH v5 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.

Ah, newer version. Would still like an ack from Samsung.

And I hit the wrong key, I did not actually apply this...

Sorry, due to an error I did not CC you to the cover letter:
https://lore.kernel.org/linux-phy/20260319223241.1351137-1-vladimir.oltean@nxp.com/

In short, the plan is to take the entire set through linux-phy once it
passes build testing.

I will have to resend v6 because of an armv7 build error I've caused for
ufs-qcom.c (which doesn't #include <linux/interrupt.h>, and relies on a
transitive inclusion from <linux/phy/phy.h>). It would be nice to get
the ack from Samsung, but I'll send the next version in the upcoming
hours regardless.

[PATCH v5 phy-next 10/27] scsi: ufs: qcom: keep parallel track of PHY power state

[Vladimir Oltean]

As explained in the similar ufs-exynos.c change, PHY consumer drivers
should not look at the phy->power_count, 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. Keep parallel track of the PHY
power state, instead of looking at a field which will become unavailable
(phy->power_count).

About treating the phy_power_off() return code: from an API perspective,
this should have probably returned void, otherwise consumers would be
stuck in a state they can't escape. The provider, phy-qcom-qmp-ufs.c,
does return 0 in its power_off() implementation. I consider it safe to
discard potential errors from phy_power_off() instead of complicating
the phy_powered_on logic.

You could even simplify the code by getting rid of the 'phy_powered_on' check
altogether. There is no real need to track the PHY power state in this driver.
It is safe to call phy_power_off() without any checks.

Ok.. as the author of commit 7bac65687510 ("scsi: ufs: qcom: Power off
the PHY if it was already powered on in ufs_qcom_power_up_sequence()"),
I assume you have hardware to test. Would you mind writing a patch that
I could pick up to replace this one with?

I suppose that the power_count test is somehow no longer necessary after
commit 77d2fa54a945 ("scsi: ufs: qcom : Refactor phy_power_on/off
calls"), but frankly I don't see it - the ufshcd state machine is a bit
too complicated for me to just statically analyze.

I believe I added the power_count check for phy_exit(). But since that got
moved, the check becomes no longer necessary.

FYI, the power_count keeps track of the balance of phy_power_on() and
phy_power_off() calls, whereas it is the init_count keeps track of
phy_init() and phy_exit() calls. They are only related to the extent
that you must respect the phy_init() -> phy_power_on() -> phy_power_off()
-> phy_exit() sequence. But in any case, both should be considered
PHY-internal fields. The "Order of API calls" section from
Documentation/driver-api/phy/phy.rst mentions the order that I just
described above, and consumers should just ensure they follow that.

Ok, so we can close this topic of "checking the power_count not needed"
by linking to the conversation which spun off here:
https://lore.kernel.org/lkml/20260325120122.265973-1-manivannan.sadhasivam@oss.qualcomm.com/

Mani, I spent some more time to figure out what's really going on with
this unexpected phy_power_off() call. Do you think you could
regression-test the patch attached?

Thanks!

Subject: [PATCH] scsi: ufs: qcom: don't call phy_power_on() before phy_init()

The Qualcomm UFS host controller driver violates the Generic PHY API
expectation, documented in section "Order of API calls" from
Documentation/driver-api/phy/phy.rst, and then tries to hide it.

The expectation is that calls must be made in the phy_init() ->
phy_power_on() -> phy_power_off() -> phy_exit() sequence.

What we actually have is:

ufshcd_init()
-> ufshcd_hba_init()
   -> ufshcd_setup_clocks(hba, true)
      -> ufshcd_vops_setup_clocks(hba, true, POST_CHANGE)
         -> ufs_qcom_setup_clocks(hba, true, POST_CHANGE)
            -> phy_power_on(phy)
   -> ufshcd_variant_hba_init()
      -> ufs_qcom_init()
         -> ufs_qcom_setup_clocks(hba, true, POST_CHANGE)
            -> phy_power_on(phy)
-> ufshcd_hba_enable()
   -> ufshcd_vops_hce_enable_notify()
      -> ufs_qcom_hce_enable_notify()
         -> ufs_qcom_power_up_sequence()
            -> if (phy->power_count) phy_power_off(phy)
            -> phy_init(phy)

This "works" because the way that the "phy_power_on was called before
phy_init\n" condition is detected in phy-core.c is if the power_count is
positive at the phy_init() call time.

By having that "if (phy->power_count) phy_power_off(phy)" logic, the
ufs-qcom.c technically sidesteps the test, but actually violates the
Generic PHY API even more (calls phy_power_on() *and* phy_power_off()
before phy_init()).

The reason why I stumbled upon this was that I was trying to remove
dereferences of phy->power_count from drivers. This is a PHY-internal
field, and using it from drivers is highly likely to be incorrect, as
this case showcases rather well.

As commit 77d2fa54a945 ("scsi: ufs: qcom : Refactor phy_power_on/off
calls") shows, this driver tries to couple the PHY power state with the
HBA clocks, for power saving reasons. I won't try to change that, I will
just move the phy_init() call earlier, to ufs_qcom_init().

After the phy_init() movement, ufs_qcom_power_up_sequence() should no
longer need to do either phy_init() nor the conditional phy_power_down().

Because the UFS variant operations are not balanced, but the PHY API
calls need to be, create wrappers for all Generic PHY API calls, and
keep a "phy_initialized" and a "phy_powered_on" boolean, so that we call
these only once, and they properly get paired with their phy_exit()/
phy_power_off() counterparts rather than leave the phy->init_count and
phy->power_count elevated.

I tested the patch. But it fails ufs_qcom_power_up_sequence() if PHY was already
powered on:

[   31.513321] qcom-qmp-ufs-phy 1d87000.phy: phy initialization timed-out
[   31.513335] ufshcd-qcom 1d84000.ufshc: Failed to calibrate PHY: -110
[   31.565273] ufshcd-qcom 1d84000.ufshc: Enabling the controller failed

Funny thing is, it didn't affect the functionality since the UFS core retries
ufshcd_hba_enable() and in the error path of ufs_qcom_power_up_sequence(),
phy_power_off() gets called and that causes the next try to succeed. So it is
evident that, if PHY was already powered ON, it should be powered off before
ufs_qcom_phy_power_on(). And due to the UFS driver design,
ufs_qcom_power_up_sequence() can get called multiple times. So we cannot just
remove phy_power_off().

Understood. Thanks for testing.

I'm still not satisfied with this level of complexity. If I get you
right, ufs_qcom_phy_power_off() is still needed because phy_calibrate()
expects a "fresh after power on" state, otherwise it fails? That would
be the second reason, apart from the first one I already identified
(undo a phy_power_on() done prior to phy_init()).

If so, could you please test the 3 patches attached (no relationship
with anything else we've exchanged thus far)?

Subject: [PATCH 1/3] phy: qcom-qmp-ufs: support dynamic gear changing

Currently, phy_set_mode_ext() on the QMP UFS PHY expects the PHY to be
powered down, and it makes no change to the hardware state, instead
phy_power_on() followed by phy_calibrate() must be run afterwards.

"Order of API calls" from Documentation/driver-api/phy/phy.rst has a
roundabout and not really clear way of saying that both calling
sequences should be supported. This was further discussed here,
documentation is pending an update:
https://lore.kernel.org/linux-phy/E1vo0mF-00000007kbg-1OeA@rmk-PC.armlinux.org.uk/

By absorbing the phy_power_off() -> ... -> phy_power_on() ->
phy_configure() surrounding sequence into phy_set_mode_ext(), consumer
drivers can be greatly simplified, and we also have a proper
self-standing phy_set_mode_ext() implementation which does not rely on
other calls to do its job.

Subject: [PATCH 2/3] scsi: ufs: qcom: call phy_init() before phy_power_on()

The Qualcomm UFS host controller driver violates the Generic PHY API
expectation, documented in section "Order of API calls" from
Documentation/driver-api/phy/phy.rst, and then tries to hide it.

The expectation is that calls must be made in the phy_init() ->
phy_power_on() -> phy_power_off() -> phy_exit() sequence.

What we actually have is:

ufshcd_init()
-> ufshcd_hba_init()
   -> ufshcd_setup_clocks(hba, true)
      -> ufshcd_vops_setup_clocks(hba, true, POST_CHANGE)
         -> ufs_qcom_setup_clocks(hba, true, POST_CHANGE)
            -> phy_power_on(phy)
   -> ufshcd_variant_hba_init()
      -> ufs_qcom_init()
         -> ufs_qcom_setup_clocks(hba, true, POST_CHANGE)
            -> phy_power_on(phy)
-> ufshcd_hba_enable()
   -> ufshcd_vops_hce_enable_notify()
      -> ufs_qcom_hce_enable_notify()
         -> ufs_qcom_power_up_sequence()
            -> if (phy->power_count) phy_power_off(phy)
            -> phy_init(phy)

This "works" because the way that the "phy_power_on was called before
phy_init\n" condition is detected in phy-core.c is if the power_count is
positive at the phy_init() call time.

By having that "if (phy->power_count) phy_power_off(phy)" logic, the
ufs-qcom.c technically sidesteps the test, but actually violates the
Generic PHY API even more (calls phy_power_on() *and* phy_power_off()
before phy_init()).

The reason why I stumbled upon this was that I was trying to remove
dereferences of phy->power_count from drivers. This is a PHY-internal
field, and using it from drivers is highly likely to be incorrect, as
this case showcases rather well.

As commit 77d2fa54a945 ("scsi: ufs: qcom : Refactor phy_power_on/off
calls") shows, this driver tries to couple the PHY power state with the
HBA clocks, for power saving reasons. I won't try to change that, I will
just move the phy_init() call earlier, to ufs_qcom_init().

After the phy_init() movement, ufs_qcom_power_up_sequence() should no
longer need to do either phy_init() nor the conditional phy_power_off().
However, phy_power_off() is still needed, for a separate reason which
will be dealt with separately.

The QMP UFS PHY can now tolerate having phy_set_mode_ext() being called
while the PHY is powered up. We no longer need to power it down, back up
and calibrate it.

Simplify ufs_qcom_power_up_sequence() by relying on just phy_set_mode_ext()
and let PHY power management be handled just by ufs_qcom_setup_clocks().

[PATCH v5 phy-next 11/27] 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 v5 phy-next 12/27] 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.

[PATCH v5 phy-next 13/27] 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.

[PATCH v5 phy-next 15/27] phy: move provider API out of public <linux/phy/phy.h>

[Vladimir Oltean]

The major goal is to hide the contents of struct phy from consumer
drivers.

The idea with "phy-props.h" is that both consumers and providers make
use of some data types. So both headers include "phy-props.h".

Some slight points of contention.

1. phy_set_bus_width(): Vinod explains that despite the current caller
   situation (9 providers, 1 consumer), it is a consumer API function.

   The use case is that the controller (for example UFS) may have
   limitations and should set the expected lanes to be used and width on
   those lanes. A number of Generic PHYs can support multiple lanes and
   multiple width so this is way for controller telling I am using this
   configuration.

2. phy-provider.h should go to include/linux/phy/ or to drivers/phy/?
   We do have 3 PHY providers outside of drivers/phy/:

   drivers/media/platform/sunxi/sun8i-a83t-mipi-csi2/sun8i_a83t_dphy.c
   drivers/gpu/drm/rockchip/dw-mipi-dsi-rockchip.c
   drivers/pinctrl/tegra/pinctrl-tegra-xusb.c

   but the practice is not encouraged, and with time, these should be
   moved to the subsystem. This is not something that I can do now.

3. We can no longer tolerate static inline helpers. Allowing these would
   make it impossible to hide the struct phy definition from consumers.
   I've made phy_get_mode(), phy_get_bus_width(), phy_set_bus_width()
   exported symbols in drivers/phy/phy-core.c.

4. This is not a change without side effects. In the transition we are
   no longer providing <linux/pm_runtime.h> at all, and
   <linux/regulator/consumer.h> to PHY consumer drivers. However, the
   in-tree dependencies should all have been resolved. Also, the
   movement of phy-provider.h to drivers/phy/ is at least "interesting"
   for out of tree PHY provider drivers (this header is not deployed by
   make headers_install). However, it seems to be what Vinod is looking
   to see.

For temporary compatibility, keep including the provider header. This
will be removed when abuses are all gotten rid of.

[PATCH v5 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 v5 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.

[PATCH v5 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 v5 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 v5 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 v5 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.

[PATCH v5 phy-next 22/27] pinctrl: tegra-xusb: include PHY provider header

[Vladimir Oltean]

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
FIXME in place. It will have to be moved, eventually.

[PATCH v5 phy-next 23/27] power: supply: cpcap-charger: include missing <linux/property.h>

[Vladimir Oltean]

This file uses dev_fwnode() without including the proper header for it,
relying on transitive header inclusion from:

drivers/power/supply/cpcap-charger.c
- include/linux/phy/omap_usb.h
  - include/linux/usb/phy_companion.h
    - include/linux/usb/otg.h
      - include/linux/phy/phy.h
        - drivers/phy/phy-provider.h
          - include/linux/of.h
            - include/linux/property.h

With the future removal of drivers/phy/phy-provider.h from
include/linux/phy/phy.h, this transitive inclusion would break.

[PATCH v5 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.

Conflicts in drivers/phy/canaan/phy-k230-usb.c with commit 8787fa1da603
("phy: usb: Add driver for Canaan K230 USB 2.0 PHY").
Conflicts in drivers/phy/eswin/phy-eic7700-sata.c with commit
67ee9ccaa34a ("phy: eswin: Create eswin directory and add EIC7700 SATA
PHY driver")

Both drivers are newly added in linux-phy/next and not present in
v7.0-rc1. The recommendation is to drop the changes in this patch and
readd them when merging into linux-phy/next.

v3->v5: none
v2->v3: add conflict resolution details

[PATCH v5 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.

Conflicts in drivers/phy/spacemit/phy-k1-pcie.c with commit 75fb1a33f9ac
("phy: move spacemit pcie driver to its subfolder"). The recommendation
is to patch drivers/phy/phy-spacemit-k1-pcie.c with the change found
here, in order for the branch to build cleanly on top of v7.0-rc1.
Then remember to patch back drivers/phy/spacemit/phy-k1-pcie.c during
the merge to linux-phy/next. VERY IMPORTANT: on v7.0-rc1, the header
path is "phy-provider.h", whereas in phy-next it is "../phy-provider.h",
due to the spacemit folder move.

Conflicts trivially in drivers/phy/qualcomm/phy-qcom-sgmii-eth.c with
commit 4ff5801f45b4 ("phy: qcom-sgmii-eth: add .set_mode() and
.validate() methods").
The recommended resolution is to keep their newly introduced adjacent
line ("+#include <linux/phy.h>" - network PHY) while removing our
"#include <linux/phy/phy.h>" - generic PHY.
This was previously brought up here:
https://lore.kernel.org/netdev/aa1lIBO3j_apIPjb@shell.armlinux.org.uk/

v4->v5: 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)

[PATCH v5 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->v5: 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
