As agreed with David, this is a continuation of his work started at [1].
Changes since his patches: HDMI schema: - Dropped generic pinctrl properties - Dropped data-lanes property, which is not supported by the HDMI driver - Switched to unevaluatedProperties - Moved clocks/regulators/supplies to condition clauses - Specified phy-names as used by existing DT files - Dropped #phy-cells - Dropped power-domains property (which is not used by the device trees) - Marked old GPIO properties as deprecated (in a separate patch)
HDMI PHY schema: - Split into QMP (msm8996) and non-QMP (other) PHY schemas - Added proper clocks/clock-names/reg/reg-names descriptions
The rest of the patches consist of the new work. They further cleanup the platform configs, remove unused supplies, etc.

Convert Qualcomm HDMI binding into HDMI TX and PHY yaml bindings.
Changes to schema: HDMI: - fixed reg-names numbering to match 0..3 instead 0,1,3,4
PHY: - moved into phy/ directory - split into QMP and non-QMP PHY schemas

Convert Qualcomm HDMI binding into HDMI TX and PHY yaml bindings.
Changes to schema: HDMI:
- fixed reg-names numbering to match 0..3 instead 0,1,3,4
PHY:
- moved into phy/ directory
- split into QMP and non-QMP PHY schemas

This should be additionalProperties:false, because you do not reference any schema. If it fails on supplies, please define the supplies in the properties list (not in the allOf:if:then) and disallow it on chosen variant (only one I guess)... if the supplies are really not possible on that variant.

Convert Qualcomm HDMI binding into HDMI TX and PHY yaml bindings.
Changes to schema: HDMI:

PHY:
- moved into phy/ directory

Fix the DTS and use only one. Do the drivers actually use it?
No, the driver just looks for the first phy entry. Should we mark phy-names as deprecated and remove its usage from actual DTs?

This should be additionalProperties:false, because you do not reference any schema. If it fails on supplies, please define the supplies in the properties list (not in the allOf:if:then) and disallow it on chosen variant (only one I guess)... if the supplies are really not possible on that variant.
The supplies are variant-specific, thus I wanted to define them in the conditional clauses. But I see your point, I'll change it.

What are the clocks for other variants? Also between 1-2 with any name?
As you asked about it... 8084 is an alias for 8974, so I'll add it here. As for the 8660... It doesn't declare any clocks, so I'll have to move this requirement to an if clause. Or maybe just split 8660 away.

Most probably I added them as they were referenced in the source (and in the example). I'll drop these two completely (and document removing them from the example).

The HDMI driver has code to configure extra GPIOs, which predates pinctrl support. Nowadays all platforms should use pinctrl instead. Neither of upstreamed Qualcomm pltforms uses these properties, so it's safe to drop them.

DB820c makes use of core-vcc-supply and core-vdda-supply, however the driver code doesn't support these regulators. Enable them for HDMI on 8996 platform.

Several platform configs use empty 'none' regulator arrays. They are not necessary, as the code will use corresponding _cnt field and skip the array completely. Drop them now.

The MSM HDMI driver has support for hpd_regs on 8x74/8084: supply regulators that are to be enabled for HPD to work. Currently these regulators contain the hpd_gdsc, which was replaced by the power-domains support and hpd-5v/hpd-5v-en, which are not used by the chip itself. They power up the ESD bridge. However it is a separate device which should be represented separately in the device tree. None of upstreamed devices support these properties. Thus drop support for them from the HDMI driver.

Since there is no more difference between the HDMI platform data between MSM8974/APQ8084/MSM8994/MSM8996, merge these configs into a single entry.
