[PATCH v3 1/5] dt-bindings: gpu: add bindings for the Microchip GFX2D GPU

From: Cyrille Pitchen
Date: Mon Nov 24 2025 - 07:12:16 EST


The Microchip GFX2D GPU is embedded in the SAM9X60 and SAM9X7 SoC family.
Describe how the GFX2D GPU is integrated in these SoCs, including
register space, interrupt and clock.
