[PATCH v4 0/9] drm/msm: Add support for Shikra GPU (A704)

[PATCH v4 0/9] drm/msm: Add support for Shikra GPU (A704)

[Akhil P Oommen]

Adreno A704 GPU found in Shikra is an IP reuse of A702 GPU with very 
minimal changes. The only KMD facing difference is the chipid and the
zap firmware which is specified via devicetree.

Mesa side support is already merged:
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/41762

Included the DT bits in the v3 revision.

Adreno A704 GPU found in Shikra is an IP reuse of A702 GPU with very

zap firmware which is specified via devicetree.

Just add the new chipid to enable support for A704 GPU in Shikra.

[PATCH v4 6/9] arm64: dts: qcom: shikra: Add GPU cooling

[Akhil P Oommen]

From: Aastha Pandey <aastha.pandey@oss.qualcomm.com>

Unlike the CPU, the GPU does not throttle its speed automatically when it
reaches high temperatures.

Set up GPU cooling by throttling the GPU speed
when reaching 115°C.
