While enabling clock, we incorrectly log 'ref clk' as 'cfg ahb clk'
Fix this since the devicetree bindings mentions it as ref clock.

Add phy and pll regulator load voting support for all supported
platforms by introducing dedicated regulator bulk data arrays
with their load values.
This ensures stable operation and proper power management for these
platforms where regulators are shared between the QMP UFS PHY and
other IP blocks by setting appropriate regulator load currents during
PHY operations.

On certain SoCs, power regulators are shared between the QMP UFS PHY
and other IP blocks. To ensure proper operation, the regulator
framework must be informed of the UFS PHY's load requirements.
This is essential because the regulator's operating mode—whether Low
Power or High Power—depends on the maximum expected load at any given
time, which the regulator driver needs to manage accordingly.
To support this, replace devm_regulator_bulk_get() with
devm_regulator_bulk_get_const() and inline the qmp_ufs_vreg_init()
function. additionally replace the array of regulator names with a
bulk regulator data structure, and utilize the init_load_uA field
provided by the regulator framework. This ensures that
regulator_set_load() is automatically invoked before the
first enable operation.

Add initial support for the Renesas RZ/T2H SoC to the R-Car Gen3 USB2 PHY
driver. The RZ/T2H SoC requires configuration of additional
hardware-specific bits for proper VBUS level control and OTG operation.
Introduce the `vblvl_ctrl` flag in the SoC-specific driver data to enable
handling of VBUS level selection logic using `VBCTRL.VBLVL` bits. This is
required for managing the VBUS status detection and drive logic based on
SoC-specific needs.

Store the SoC-specific driver data pointer (struct rcar_gen3_phy_drv_data)
directly in struct rcar_gen3_chan instead of copying individual flags into
separate channel members.
Obtain the drvdata with of_device_get_match_data() in probe and assign it
to channel->phy_data. Update all call sites to reference
`channel->phy_data->*` for SoC-specific behaviour (for example no_adp_ctrl
and utmi_ctrl). Remove the redundant soc_no_adp_ctrl and utmi_ctrl fields
from struct rcar_gen3_chan.
This simplifies the probe path, reduces duplication, and makes it easier
to extend the driver with additional platform-specific fields in the
future.

Register a typec mux in order to change the PHY mode on the Type-C
mux events depending on the mode and the svid when in Altmode setup.
The DisplayPort phy should be left enabled if is still powered on
by the DRM DisplayPort controller, so bail out until the DisplayPort
PHY is not powered off.
The Type-C Mode/SVID only changes on plug/unplug, and USB SAFE states
will be set in between of USB-Only, Combo and DisplayPort Only so
this will leave enough time to the DRM DisplayPort controller to
turn of the DisplayPort PHY.

So far we set a number of expected Allwinner USB PHY instances for any
given compatible string, and would fail if we do not find every PHY
described properly in the DT (missing reset/PMU/clocks).
This is somewhat redundant, as the DT only describes the resources for
the implemented PHYs, but goes in line with being strict about firmware
descriptions, and rather fixing things in the driver code, based on the
compatible string.
However this causes issues when we make a mistake, like we did recently
on the A523: there are actually three USB PHYs, not two, as we assumed.
Changing the number in the driver and the compatible string would cause
all kinds of compatibility issues, both with older and newer DTs.
To avoid problems with newer kernels and older or newer DTs, we can change
the driver code to deduce the number of PHY instances from what's
described in the DT. This has the added advantage of not requiring new
compatible strings for new SoCs when just the number of PHYs change, which
already happened and might occur again in the future.
Drop the num_phys member from the config struct, and remove the fixed
number of PHYs from each SoC's config description. Then enumerate the
usb<x>_reset properties for all of the maximum four PHY instances, and
just stop once we cannot find such a property anymore.
The binding describes the reset property as mandatory for each PHY
instance, and each DT in the kernel tree matches exactly the num_phys
value in the current driver code, so we can rely on that.
Apart from being more future proof, this will solve the A523 mishap:
Older DTs would just describe two PHYs, whereas newer ones would feature
all three of them. In any case we would get a valid number, matching the
other nodes in the DT. Older kernels would always enumerate two PHYs,
which at least does not cause any regressions.

property "qcom,tune-usb2-preem" is for EUSB2_TUNE_USB2_PREEM
property "qcom,tune-usb2-amplitude" is for EUSB2_TUNE_IUSB2
The downstream correspondence is as follows:
EUSB2_TUNE_USB2_PREEM: Tx pre-emphasis tuning
EUSB2_TUNE_IUSB2: HS trasmit amplitude
EUSB2_TUNE_SQUELCH_U: Squelch detection threshold
EUSB2_TUNE_HSDISC: HS disconnect threshold
EUSB2_TUNE_EUSB_SLEW: slew rate

The current configuration used for the IPQ5332 M31 USB PHY fails the
Near End High Speed Signal Quality compliance test. To resolve this,
update the initialization sequence as specified in the Hardware Design
Document.

The eUSB2 HPG version 1.0.2 asks to clear bits [7:1] on all targets.
Implement that change in the driver to follow.

As per a commit from Qualcomm's downstream 6.1 kernel[0], the init
sequence is missing setting the CMN_CTRL_OVERRIDE_EN bit back to 0 at
the end, as per the 'latest' HPG revision (as of November 2023).

pcie_conf is used to touch TEST_WRITE strobe signal. This signal should
be enabled, a little time waited, and then disabled. Current code clearly
was copy-pasted and never disables the strobe signal. Adjust the define.
While at it, remove PHY_CFG_RD_MASK which has been unused since
64cdc0360811 ("phy: rockchip-pcie: remove unused phy_rd_cfg function").
