[PATCH v3 0/3] Support for Adreno 623 GPU

[PATCH v3 0/3] Support for Adreno 623 GPU

[Akhil P Oommen]

This series adds support for A623 GPU found in QCS8300 chipsets. This
GPU IP is very similar to A621 GPU, except for the UBWC configuration
and the GMU firmware.

Both DT patches are for Bjorn and the dt-bindings update for Rob Clark
to pick up.

---
Changes in v3:
- Rebased on top of v6.15-rc5
- Dropped drm-msm patches since they are merged in v6.15
- Correct GMU opp table in dt (Konrad)
- Remove smmu_clk from gmu clock list (Konrad)
- Update dt-bindings yaml with a new patch#1
- Link to v2: https://lore.kernel.org/r/20250228-a623-gpu-support-v2-0-aea654ecc1d3@quicinc.com

Changes in v2:
- Fix hwcg config (Konrad)
- Split gpucc reg list patch (Rob)
- Rebase on msm-next tip
- Link to v1: https://lore.kernel.org/r/20250213-a623-gpu-support-v1-0-993c65c39fd2@quicinc.com

I don't understand. 623 is already here, you document nothing new. This
makes no sense, I never, absolutely never reviewed code like this.

Aah! my bad. This is actually a new patch which I mentioned in the cover
letter: "Update dt-bindings yaml with a new patch#1"

I will update the subject and drop the R-b tag.

The clock list is different for 623. We are removing smmu_clk for 623.
