Add DSI controller for Qualcomm SM8750 SoC which is quite different from
previous (SM8650) generation.
It does not allow the display clock controller clocks like "byte" and
"pixel" to be reparented to DSI PHY PLLs while the DSI PHY PLL is not
configured (not prepared, rate not set). Therefore
assigned-clock-parents are not working here and driver is responsible
for reparenting clocks with proper procedure. These clocks are now
inputs to the DSI controller device.
Except that SM8750 DSI comes with several differences, new blocks and
changes in registers, making it incompatible with SM8650.

Currently we do not differentiate between the various users of the
qcom,mdss-dsi-ctrl. The driver is flexible enough to operate from one
compatible string but, the hardware does have some significant differences
in the number of clocks.
To facilitate documenting the clocks add the following compatible strings
- qcom,apq8064-dsi-ctrl
- qcom,msm8916-dsi-ctrl
- qcom,msm8953-dsi-ctrl
- qcom,msm8974-dsi-ctrl
- qcom,msm8996-dsi-ctrl
- qcom,msm8998-dsi-ctrl
- qcom,sc7180-dsi-ctrl
- qcom,sc7280-dsi-ctrl
- qcom,sdm660-dsi-ctrl
- qcom,sdm845-dsi-ctrl
- qcom,sm8150-dsi-ctrl
- qcom,sm8250-dsi-ctrl
- qcom,sm8350-dsi-ctrl
- qcom,sm8450-dsi-ctrl
- qcom,sm8550-dsi-ctrl
- qcom,qcm2290-dsi-ctrl
Deprecate qcom,dsi-ctrl-6g-qcm2290 in favour of the desired format while we
do so.
Several MDSS yaml files exist which document the dsi sub-node.
For each existing SoC MDSS yaml, provide the right dsi compat string.

When converting from .txt to .yaml we didn't include descriptions for the
existing regulator supplies.
- vdd
- vdda
- vddio
Add those descriptions into the yaml now as they were prior to the
conversion. In the .txt description we marked these regulators as required,
however, that requirement appears to have been in error.
Taking the example of sc7180-trogdor-wormdingler.dtsi. The avdd and avee
come from GPIO controlled external regulators, not the SoC and in this case
there's no need for vddio to power an I/O bus. Similarly the regulators for
the LCD are controlled by the panel driver not by the dsi-ctrl driver.
It would be possible to connect a different type of panel to the DSI bus
here in which case we may or may not want to make use of vdd, vdda or
vddio.
This is also the case for older chipsets like apq8064, msm8916 etc the vdd*
regulators in the dsi-ctrl block are helpers not dependencies.
Add the description of vdd, vdda and vddio back in for the existing
upstream dts where vdd, vdda or vddio are already declared but, don't
declare those regulators required - they are not SoC requirements.

power-domain is required for the sc7180 dispcc GDSC but not every qcom SoC
has a similar dependency for example the apq8064.
Most Qcom SoC's using mdss-dsi-ctrl seem to have the ability to
power-collapse the MDP without collapsing DSI.
For example the qcom vendor kernel commit for apq8084, msm8226, msm8916,
msm8974.
7b5c011a77
"ARM: dts: msm: add mdss gdsc supply to dsi controller device
It is possible for the DSI controller to be active when MDP is
power collapsed. DSI controller needs to have it's own vote for
mdss gdsc to ensure that gdsc remains on in such cases."
This however doesn't appear to be the case for the apq8064 so we shouldn't
be marking power-domain as required in yaml checks.

Adding in msm8939 which is based msm8916 dtsi I stumbled across a binding
check complaining about the phy name for msm8916 which we were reusing for
msm8939.
The currently inconsistent upstream dtsi naming of "dsi" and "dsi-phy" is
not captured in the yaml for this driver.
The driver however doesn't care about the name of DSI phy, hence the yaml
check is redundant.
Both Krzysztof and Rob suggested we could drop the phy-names entirely if it
really isn't a dependency.
So, drop the inconsistent and unnecessary phy-names field from the yaml.
