corresponding set flags are set
According documentation of phy_configure_opts_dp, at the configure
stage, link rates should only be verify/configure when set_rate
flag is set, the same applies to lanes and voltage.
So do it as the documentation says.
Because voltage setting depends on the lanes, link rates set
previously, so record the link rates and lanes at it's verify stage.

Ensure the PHY reset and perst is asserted during power-off to
guarantee it is in a reset state upon repeated power-on calls. This
resolves an issue where the PHY may not properly initialize during
subsequent power-on cycles. Power-on will deassert the reset at the
appropriate time after tuning the PHY parameters.
During suspend/resume cycles, we observed that the PHY PLL failed to
lock during resume when the CPU temperature increased from 65C to 75C.
The observed errors were:
phy phy-32f00000.pcie-phy.3: phy poweron failed --> -110
imx6q-pcie 33800000.pcie: waiting for PHY ready timeout!
imx6q-pcie 33800000.pcie: PM: dpm_run_callback(): genpd_resume_noirq+0x0/0x80 returns -110
imx6q-pcie 33800000.pcie: PM: failed to resume noirq: error -110
This resulted in a complete CPU freeze, which is resolved by ensuring
the PHY is in reset during power-on, thus preventing PHY PLL failures.

Remove the switch statement and base perst release on whether it is
found in the device tree. The probe function fails without the reset
property, making it mandatory. Therefore, always release reset
independent of the variant.
This does not change the behavior of the driver but reduces driver
complexity and allows for easier future modifications.

Despite the compatible already being listed in the bindings, the PHY
driver never gained explicit support for it. This is especially a
problem because the explicitly listed PHY addresses need to be specified

To solve this, add the compatible, and a PHY config, with the address
gleaned from rk3576.dtsi.

Older Exynos designs, like Exynos5422, do not have USB Type-C and the
USB DRD PHY does not really need CONFIG_TYPEC for these devices at all.
Incorrectly added optional dependency on CONFIG_TYPEC caused this driver
to be missing for exynos_defconfig and as result Exynos5422-based boards
like Hardkernel Odroid HC1 failed to probe USB.

As reported by Damon Ding, the phy_get_mode() call doesn't work as
expected unless the PHY driver has a .set_mode() call. This prompts PHY
drivers to have empty stubs for .set_mode() for the sake of being able
to get the mode.
Make .set_mode() callback truly optional and update PHY's mode even if
it there is none.

Use syscon_regmap_lookup_by_phandle_args() which is a wrapper over
syscon_regmap_lookup_by_phandle() combined with getting the syscon
argument. Except simpler code this annotates within one line that given
phandle has arguments, so grepping for code would be easier.
There is also no real benefit in printing errors on missing syscon
argument, because this is done just too late: runtime check on

static/build-time check for this already.

To make USB runtime suspend work when a UDC has been bound, the phy
needs to inform the USBDRD controller (DWC3) that Vbus and bvalid are
gone, so that it can in turn raise the respective gadget interrupt with
event == DWC3_DEVICE_EVENT_DISCONNECT, which will cause the USB stack
to clean up, allowing DWC3 to enter runtime suspend.
On e850 and gs101 this isn't working, as the respective signals are not
directly connected, and instead this driver uses override bits in the
PHY IP to set those signals. It currently forcefully sets them to 'on',
so the above mentioned interrupt will not be raised, preventing runtime
suspend.
To detect that state, update this driver to act on the TCPC's
orientation signal - when orientation == NONE, Vbus is gone and we can
clear the respective bits. Similarly, for other orientation values we
re-enable them.
This makes runtime suspend work on platforms with a TCPC (like Pixel6),
while keeping compatibility with platforms without (e850-96).
With runtime suspend working, USB-C cable orientation detection now
also fully works on such platforms, and the link comes up as Superspeed
as expected irrespective of the cable orientation and whether UDC /
gadget are configured and active.

gs101's SS phy needs to be configured differently based on the
connector orientation, as the SS link can only be established if the
mux is configured correctly.
The code to handle programming of the mux is in place already, this commit
now adds the missing pieces to subscribe to the Type-C orientation
switch event.
Note that for this all to work we rely on the USB controller
re-initialising us. It should invoke our .exit() upon cable unplug, and
during cable plug we'll receive the orientation event after which we
expect our .init() to be called.
Above reinitialisation happens if the DWC3 controller can enter runtime
suspend automatically. For the DWC3 driver, this is an opt-in:
echo auto > /sys/devices/.../11110000.usb/power/control
Once done, things work as long as the UDC is not bound as otherwise it
stays busy because it doesn't cancel / stop outstanding TRBs. For now
we have to manually unbind the UDC in that case:
echo "" > sys/kernel/config/usb_gadget/.../UDC
Note that if the orientation-switch property is missing from the DT,
the code will behave as before this commit (meaning for gs101 it will
work in SS mode in one orientation only). Other platforms are not
affected either way.

USB SS lanes need to be configured based on the connector orientation -
at most two lanes will be in use for USB (and the remaining two for
alternate modes like DP).
For the USB link to come up in SS, the lane configuration registers
have to be programmed accordingly.
While we still need a way to be notified of the actual connector
orientation and then reprogram the registers accordingly (at the moment
the configuration happens just once during phy_init() and never again),
we can prepare the code doing the configuration to take the orientation
into account.
Do so.
Note: the mutex is needed to synchronize this with the upcoming
connector orientation callback.

This code's intention is to configure lane0 and lane2 tunings, but for
lane2 there is a typo and it ends up tuning something else.
Fix the typo, as it doesn't appear to make sense to apply different
tunings for lane0 vs lane2.
The same typo appears to exist in the bootloader, hence we restore the
original value in the typo'd registers as well. This can be removed
once / if the bootloader is updated.
Note that this is incorrect in the downstream driver as well - the
values had been copied from there.

The phy needs to know its identity in the system (phy0 or phy1 on rk3588)
for some actions and the driver currently contains code abusing of_alias

Devicetree aliases are always optional and should not be used for core
device functionality, so instead keep a list of phys on a soc in the
of_device_data and find the phy-id by comparing against the mapped

This reverts commit 3dd075fe8ebbc6fcbf998f81a75b8c4b159a6195.
Tomasz has reported that his device, Generalplus Technology Inc. 808 Camera,
with ID 1b3f:2002, stopped being detected:
$ ls -l /dev/video*
zsh: no matches found: /dev/video*
[ 7.230599] usb 3-2: Found multiple Units with ID 5
This particular device is non-compliant, having both the Output Terminal
and Processing Unit with ID 5. uvc_scan_fallback, though, is able to build
a chain. However, when media elements are added and uvc_mc_create_links
call uvc_entity_by_id, it will get the incorrect entity,
media_create_pad_link will WARN, and it will fail to register the entities.
In order to reinstate support for such devices in a timely fashion,
reverting the fix for these warnings is appropriate. A proper fix that
considers the existence of such non-compliant devices will be submitted in
a later development cycle.

When block drivers or the core block code perform allocations with a
frozen queue, this could try to recurse into the block device to
reclaim memory and deadlock. Thus all allocations done by a process
that froze a queue need to be done without __GFP_IO and __GFP_FS.
Instead of tying to track all of them down, force a noio scope as
part of freezing the queue.
Note that nvme is a bit of a mess here due to the non-owner freezes,
and they will be addressed separately.
