[PATCH v2 0/5] arm64: dts: qcom: sm8450-hdk: enable HDMI output

[Dmitry Baryshkov]

Add device tree nodes for MDSS, DPU and DSI devices on Qualcomm SM8450
platform. Enable these devices and add the HDMI bridge configuration on
SM8450 HDK.

Changes since v1:
- Reorder properties, making status the last one
- Rename opp nodes to follow the schema
- Renamed display-controller and phy device nodes
- Dropped phy-names for DSI PHYs
- Renamed DSI and DSI PHY labels to include mdss_ prefix
- Renamed 3v3 regulator device node to add -regulator suffix

[PATCH v2 1/5] arm64: dts: qcom: sm8450: add RPMH_REGULATOR_LEVEL_LOW_SVS_D1

[Dmitry Baryshkov]

Add another power saving state used on SM8450. Unfortunately adding it
in proper place causes renumbering of all the opp states in sm8450.dtsi

[PATCH v2 2/5] arm64: dts: qcom: sm8450: add display hardware devices

[Dmitry Baryshkov]

Add devices tree nodes describing display hardware on SM8450:
- Display Clock Controller
- MDSS
- MDP
- two DSI controllers and DSI PHYs

This does not provide support for DP controllers present on SM8450.
