[PATCH RFC v2 0/3] arm64: dts: qcom: eliza: Add display

[PATCH RFC v2 0/3] arm64: dts: qcom: eliza: Add display

[Krzysztof Kozlowski]

Dependencies
============
1. Depends on USB patches, which are being reviewed, therefore marking it
as RFC as it cannot be applied.
https://lore.kernel.org/all/20260331-eliza-adsp-usb-v1-0-d8a251be20c3@oss.qualcomm.com/

2. Bindings were mostly merged, except change to SM8650 DP bindings
   here:
https://lore.kernel.org/all/20260405-dts-qcom-display-regs-v2-0-34f4024c65dc@oss.qualcomm.com/

Changes in v2:
==============
- New Patch #3: enable display port
- Add tags
- Add CX power domains
- Implement review:
   - correct address ranges for DPU, DSI PHY and DP;
   - add DP address spaces for P2, P3, MST2 and MST3;
   - wrap lines

- Note that DP will work only after adding USB mux, for which I have
  work in progress in github qualcomm-linux/kernel-topics.git, branch
  early/hwe/eliza.  It depends on unfinished I2C support.

- Link to v1: https://patch.msgid.link/20260331-dts-qcom-eliza-display-v1-0-856f0b66b282@oss.qualcomm.com

Description
===========
DSI panel and DP work fine.

HDMI is not yet ready, because of lack of hardware with HDMI (work in
progress).

Best regards,
Krzysztof

[PATCH RFC v2 1/3] arm64: dts: qcom: eliza: Add display (MDSS) with Display CC

[Krzysztof Kozlowski]

Add device nodes for almost entire display: MDSS, DPU, DSI, DSI PHYs,
DisplayPort and Display Clock Controller.

Missing pieces are HDMI PHY and HDMI controller.

Lack of hardware for HDMI testing, but the work on drivers is in
progress.
