[PATCH v3 0/6] SDM670 display subsystem support

[PATCH v3 0/6] SDM670 display subsystem support

[Richard Acayan]

Changes since v2 (20231003012119.857198-9-mailingradian@gmail.com):
 - rebase on series and reference generic sblk definitions (5/6)
 - add interconnects properties in example (3/6)
 - remove phy-names properties from dtsi (6/6)
 - accumulate review tags (4/6, 6/6)

Changes since v1 (20230925232625.846666-9-mailingradian@gmail.com):
 - prefix dsi1 labels with `mdss_` in example dts (3/6)
 - make all parts of catalog entry const (5/6)
 - add spaces before closing brackets on same line (5/6)
 - join opening and closing braces on the same line in dsc array (5/6)

This series adds support for the display subsystem on the Snapdragon
670. It is based on an earlier patch a few versions back, which had
missing device tree bindings and device tree changes.

There is a separate IOMMU patch which adds the MDSS compatible to a
workaround.

This series depends on https://patchwork.freedesktop.org/series/119804/.

[PATCH v3 2/6] dt-bindings: display/msm: sdm845-dpu: Describe SDM670

[Richard Acayan]

The SDM670 display controller has the same requirements as the SDM845
display controller, despite having distinct properties as described in
the catalog. Add the compatible for SDM670 to the SDM845 controller.

[PATCH v3 5/6] drm/msm/dpu: Add hw revision 4.1 (SDM670)

[Richard Acayan]

The Snapdragon 670 uses similar clocks (with one frequency added) to the
Snapdragon 845 but reports DPU revision 4.1. Add support for this DPU
with configuration from the Pixel 3a downstream kernel.

Since revision 4.0 is SDM845, reuse some configuration from its catalog
entry.
