[PATCH v3 0/4] HDMI TX support in msm8998

[Marc Gonzalez]

DT bits required for HDMI TX support in APQ8098 (msm8998 cousin)

Supersedes <a2cb1290-9e01-4136-9592-ce439b1096b6@freebox.fr>

Changes in v3
- Address Rob's comments on patch 2:
  - 'maxItems: 5' for clocks in the 8996 if/then schema
  - match the order of 8996 for the clock-names in common

Why is the patch titled display/msm, this is phy patch and it should be
tagged as such..

Pls update

I assume this refers to:
"Why is the patch titled display/msm, this is phy patch and it should be
tagged as such."

I always copy what others have done before me:

$ git log --oneline Documentation/devicetree/bindings/display/msm/hdmi.yaml
27339d689d2f9 dt-bindings: display/msm: hdmi: add qcom,hdmi-tx-8998
6c04d89a6138a dt-bindings: display/msm: hdmi: mark hdmi-mux-supply as deprecated
e3c5ce88e8f93 dt-bindings: display/msm: hdmi: mark old GPIO properties as deprecated
2f14bc38d88a4 dt-bindings: display/msm: hdmi: split and convert to yaml

Are you saying we should diverge from the previous nomenclature?

Regards.

This one is fine. For the phy bindings please use phy: prefix.
