As agreed with David, this is a continuation of his work started at [1].
Changes since v2:
- Deprecated usage of phy-names for HDMI node, added two patches to
remove this property from DT files,
- Fixed the uninitialized variable access in hpd_gpio code.
Changes since v1:
- Dropped quotes in $id/$schema
- Sorted out compat strings alphabetically
- Removed obvious descriptions
- Removed undocumented qcom,hdmi-tx-ddc-* properties
- Switched to additionalProperties
- Fixed IRQ and GPIO flags in the schema example
- Added 8084 and 8660 variants to qcom,hdmi-phy-other.yaml conditional
- Marked hdmi-mux-supply as deprecated (and dropped it from
apq8064-ifc6410.dtsi)
- Reused 8960 regulator/clock configs for 8x60 (verified against msm-3.4
kernel)
Changes since David's 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
- dropped qcom,tx-ddc-* from example, they were not documented
- make phy-names deprecated, drop it from the examples
PHY:
- moved into phy/ directory
- split into QMP and non-QMP PHY schemas

hdmi-mux-supply is not used by the SoC's HDMI block, it is thought to
power up the external logic. Thus it should not be a part of HDMI
bindings, but it should be declared at some other device in the DT (like
HDMI mux, bridge, etc). Mark it as deprecated.

pinctrl support. Nowadays all platforms should use pinctrl instead.
Neither of upstreamed Qualcomm platforms uses these properties, so it's
safe to drop them.

As a second thought, I think I'll merge it as is for now and fix all
error messages while moving the resource allocation to the _probe()
function. There are few other places where we are printing the
EPROBE_DEFER error code.

* [PATCH v3 07/14] drm/msm/hdmi: enable core-vcc/core-vdda-supply for 8996 platform

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.
Fixes: 0afbe59edd3f ("drm/msm/hdmi: Add basic HDMI support for msm8996")

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.

Declare that 8x60 HDMI PHY uses the core-vdda regulator and slave_iface
clock (this is the same config as is used by the 8960).

The HDMI driver doesn't use the phy-names to identify the PHY. Different
Qualcomm platforms have used different names for the PHY. So, we are
deprecating phy-names propertty of the HDMI device and dropping them
from existing DTs.
