[PATCH v2 0/3] drm/msm: Add support for Shikra GPU (A704)

[PATCH v2 0/3] 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

The dependencies for the devicetree patches are still on the mailing
lists. So I will send that separately.

[PATCH v2 2/3] drm/msm/adreno: Add support for A704 GPU

[Akhil P Oommen]

From: Aditya Sherawat <asherawa@qti.qualcomm.com>

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.

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