drm/msm/dpu: add CDM related logic to dpu_hw_ctl layer
CDM block will need its own logic to program the flush and active bits in the dpu_hw_ctl layer. Make necessary changes in dpu_hw_ctl to support CDM programming. changes in v3: - drop unused cdm_active as reported by kbot - retained the R-b as its a trivial change changes in v2: - remove unused empty line - pass in cdm_num to update_pending_flush_cdm() Reported-by: kernel test robot <lkp@intel.com> Closes: https://lore.kernel.org/oe-kbuild-all/202312102047.S0I69pCs-lkp@intel.com/ Signed-off-by: Abhinav Kumar <quic_abhinavk@quicinc.com> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Patchwork: https://patchwork.freedesktop.org/patch/571829/ Link: https://lore.kernel.org/r/20231212205254.12422-11-quic_abhinavk@quicinc.com Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>
