[PATCH 1/7] drm/msm/dpu: enable PINGPONG TE operations only when supported by HW

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The DPU_PINGPONG_TE bit is set for all PINGPONG blocks on DPU < 5.0.
Rather than checking for the flag, check for the presense of the
corresponding interrupt line.
