[PATCH v3 0/6] Commonize Redmi 5A for 4A and GO

[PATCH v3 0/6] Commonize Redmi 5A for 4A and GO

[Barnabás Czémán]

Redmi 5A is similar device like Redmi GO and Redmi 4A.

This patch series commonize it to avoid code duplications.

Differences between 4A and 5A:
- Different charger and fg
- Different displays panel but same resolution
- Different speaker codec configuration (awinic-mode)

Differences between GO and 5A:
- Different charger and fg
- Different speaker codec (aw87319)

Additional changes:
- Update Redmi 5A board-id for support nougat and oreo bootloader.
- Add Goodix touch controller support for all variants.
  The necessary touch controller can be enabled by devicetree overlay or lk2nd.

Changes in v3:
- xiaomi-tiare: Remove l23 regulator override, add min-volateg for l22.
- xiaomi-riva: use generic names for fg and charger.
- xiaomi-wingtech: Use memory-region for framebuffer.
- squash riva addition commit to comminization commit.
- Link to v2: https://lore.kernel.org/r/20260310-riva-common-v2-0-3bfc23996857@mainlining.org

Changes in v2:
- Rename msm8917-xiaomi-riva-common to msm8917-xiaomi-wingtech.
- Split goodix touch controller addition to a different commit.
- Disable touch controllers by default.
- Split new Redmi 5A devicetree to a different commit.
- Fix Redmi 4A board-id.
- Update riva board-id to make it able to run all bootloader version.
- Squash the devicetree bindings.
- Link to v1: https://lore.kernel.org/r/20260305-riva-common-v1-0-436f1f4b7399@mainlining.org

[PATCH v3 1/6] arm64: dts: qcom: msm8917-xiaomi-riva: Fix board-id for all bootloader

[Barnabás Czémán]

Redmi 5A comes with multiple bootloader versions where the expected
board-id is different.
Change the board-id to unified form what works on both bootloader
version.

[PATCH v3 2/6] arm64: dts: qcom: Make a common base from Redmi 5A

[Barnabás Czémán]

Redmi 5A was made by wingtech like Redmi 4A (rolex) and Redmi GO (tiare).
They are very similar, make a common base from riva for avoid
unnecessary code duplications.
