[PATCH v6 1/2] dt-bindings: gpu: Add 'resets' property for GPU initialization

[Michal Wilczynski]

All IMG Rogue GPUs include a reset line that participates in the
power-up sequence. On some SoCs (e.g., T-Head TH1520 and Banana Pi
BPI-F3), this reset line is exposed and must be driven explicitly to
ensure proper initialization.

To support this, add a 'resets' property to the GPU device tree
bindings.
