[Freedreno] [PATCH 4/7] drm/msm/a5xx: Reset VBIF before PC only on A510 and A530

2020-09-26 Thread kholk11
From: AngeloGioacchino Del Regno Resetting the VBIF before power collapse is done to avoid getting bogus FIFO entries during the suspend sequence or subsequent resume, but this is doable only on Adreno 510 and Adreno 530, as the other units will tendentially lock up. Especially on Adreno 508,
