[v2] Imagination BXS-4-64 MC1 GPU support

[PATCH v2 07/21] arm64: dts: ti: k3-am62: New GPU binding details

Posted by Matt Coster 5 days, 23 hours ago

Use the new compatible string introduced earlier (in "dt-bindings: gpu:
img: More explicit compatible strings") and add a name to the single power
domain for this GPU (introduced in "dt-bindings: gpu: img: Power domain
details").

Do not mix DTS with code. It always goes either to end of patchset or
entirely separate.

To be clear: this cannot be merged into DRM.

Definitely NAK, breaks users and nothing in commit msg provides any help
on that, including why or how it affects potential users.
