[PATCH v3 0/5] dt-bindings: msm/dp: Add support for 4 pixel streams
Posted by Jessica Zhang 2 months, 2 weeks ago
On some MSM chipsets, the display port controller is capable of supporting
up to 4 streams.

To drive these additional streams, the pixel clocks for the corresponding
stream needs to be enabled.

Fixup the documentation of some of the bindings to clarify exactly which
stream they correspond to, then add the new bindings and device tree
changes.

---
Changes in v3:
- Fixed dtschema errors (Rob Herring)
- Documented all pixel stream clocks (Dmitry)
- Ordered compatibility list alphabetically (Dmitry)
- Dropped assigned-clocks too (Dmitry)
- Link to v2: https://lore.kernel.org/r/20250530-dp_mst_bindings-v2-0-f925464d32a8@oss.qualcomm.com

Changes in v2:
- Rebased on top of next-20250523
- Dropped merged maintainer patch
- Added a patch to make the corresponding dts change to add pixel 1
  stream
- Squashed pixel 0 and pixel 1 stream binding patches (Krzysztof)
- Drop assigned-clock-parents bindings for dp-controller (Krzysztof)
- Updated dp-controller.yaml to include all chipsets that support stream
  1 pixel clock (Krzysztof)
- Added missing minItems and if statement (Krzysztof)
- Link to v1: https://lore.kernel.org/r/20241202-dp_mst_bindings-v1-0-9a9a43b0624a@quicinc.com

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Base: base-commit 7a88d609b069b7d2f4d10113b18fea02921bedb1 not known, ignoring
 Base: attempting to guess base-commit...
 Base: tags/v6.16-rc2-698-g6b93840116df (exact match)

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)
