On QCM2290 chipset DPU does not support UBWC. Add a dpu cap to indicate this and do not expose compressed formats in this case. changes since RFC: - use ubwc enc and dec version of mdss_data instead of catalog to decide if ubwc is supported Signed-off-by: Abhinav Kumar <quic_abhinavk@quicinc.com> --- drivers/gpu/drm/msm/disp/dpu1/dpu_plane.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-)
