[RFC PATCH 4/4] drm/panthor: Use GPU_COMMAND.FLUSH_CACHES for cache maintenance

2024-12-19 Thread Karunika Choo
This patch adds support for performing cache maintenance operations via the GPU_CONTROL.GPU_COMMAND register instead of using FLUSH_PT or FLUSH_MEM commands from the AS_COMMAND register. This feature is enabled when the HW feature bit (PANTHOR_HW_FEATURE_GPU_CTRL_CACHE_FLUSH) is set. Signed-off-by
