[PATCH v2 5/6] dt-bindings: clock: qcom: Document Nord GPU clock controllers
From: Taniya Das
Date: Tue Jul 21 2026 - 03:08:37 EST
Add Device Tree binding documentation for the GPU clock controllers
on the Qualcomm Nord platform.
The platform includes two GPU clock controller instances, GPUCC and
GPUCC2. Document the compatible strings for both controllers.
