Update Qualcomm DT files in order to declare extra stream pixel clocks
and extra register resources used on these platforms to support
DisplayPort MST.
The driver will continue to work with the old DTS files as even after
adding MST support the driver will have to support old DTS files which
didn't have MST clocks.

SM6350 doesn't have MST support, as such in DT schema it has been
switched to use SC7180 as a fallback compatible. Make DT file implement
this change. DisplayPort on SC7180 has been supported long ago (and long
before we added support for DP on SM8350). The driver will continue to
work with the old DTS (having qcom,sm8350-dp fallback compatible) as
even after adding MST support the driver will have to support old SM8350
DTS which didn't have MST clocks.

MTP8750 rev 2.0 (power grid v8) boards come as two different variants
with different WiFi chips: WCN7850 and WCN786x. WCN7850 is already
supported by the kernel, but WCN786x is not. Both of the board variants
are considered newest revisions and the difference is only in MCN
numbers and internal codenames.
Add WCN7850 WiFi and Bluetooth to the MTP8750, stating that this DTS
represents the WCN7850 variant. The S4D and S5F regulators should
operate at 0.85 V, thus adjust lower constraint and regulator name.

IRIS firmware for x1e80100-crd is already upstream in linux-firmware in the
default path, so enable IRIS for the CRD to accelerate video decoding.
It looks like the X1P CRD might need a different IRIS firmware (possibly
even changes in the Linux kernel driver), so keep it local to the X1E CRD
for now.

The reset and IOMMU management for remoteprocs like IRIS is implemented in
the hypervisor for older targets such as X1E [1]. When booting Linux/KVM
directly in EL2, this functionality is missing and the PAS interface
normally used by IRIS to boot the video firmware is not working.
The Venus driver supports starting the video firmware without using the PAS
interface. The same code also works for X1E when using KVM. However, for
the new IRIS dt-bindings it was decided to avoid using the dummy
"video-firmware" node in the device tree to describe the IOMMU [2].
Discussion is still ongoing how to describe this properly [3].
To avoid regressions when running using KVM, add a TODO in x1-el2.dtso for
now and disable IRIS even when it was enabled by the board.

Add the IRIS video codec to accelerate video decoding/encoding. Copied
mostly from sm8550.dtsi, only the opp-table is slightly different for X1E.
For opp-240000000, we need to vote for a higher OPP on one of the power
domains, because the voltage requirements for the PLL and the derived
clocks differ (sm8550.dtsi has the same).

On most MSM8939 devices, the bootloader already initializes the display to
show the boot splash screen. In this situation, MDSS is already configured
and left running when starting Linux. To avoid side effects from the
bootloader configuration, the MDSS reset can be specified in the device
tree to start again with a clean hardware state.
The reset for MDSS is currently missing in msm8939.dtsi, which causes
errors when the MDSS driver tries to re-initialize the registers:
dsi_err_worker: status=6
dsi_err_worker: status=6
dsi_err_worker: status=6
...
It turns out that we have always indirectly worked around this by building
the MDSS driver as a module. Before v6.17, the power domain was temporarily
turned off until the module was loaded, long enough to clear the register
contents. In v6.17, power domains are not turned off during boot until
sync_state() happens, so this is no longer working. Even before v6.17 this
resulted in broken behavior, but notably only when the MDSS driver was
built-in instead of a module.

This does not match the node name.
Update the reg property to use the correct base address 0x17c27000,

Enable the first USB controller in device mode on the Lemans EVK
board and configure the associated LDO regulators to power
the PHYs accordingly.
The USB port is a Type-C port controlled by HD3SS3320 port controller.
The role switch notifications would need to be routed to glue driver by
adding an appropriate usb-c-connector node in DT. However in the design,
the vbus supply that is to be provided to connected peripherals when
port is configured as an DFP, is controlled by a GPIO.
There is also one ID line going from Port controller chip to GPIO-50 of
the SoC. As per the datasheet of HD3SS3320:
"Upon detecting a UFP device, HD3SS3220 will keep ID pin high if VBUS is
not at VSafe0V. Once VBUS is at VSafe0V, the HD3SS3220 will assert ID
pin low. This is done to enforce Type-C requirement that VBUS must be
at VSafe0V before re-enabling VBUS."
The current HD3SS3220 driver doesn't have this functionality present. So,
putting the first USB controller in device mode for now. Once the vbus
control based on ID pin is implemented in hd3ss3220.c, the
usb-c-connector will be implemented and dr mode would be made OTG.
