Add support for DSC 1.2 by providing the necessary hooks to program the DPU DSC 1.2 encoder. Changes in v3: -- fixed kernel test rebot report that "__iomem *off" is declared but not used at dpu_hw_dsc_config_1_2() -- unrolling thresh loops Changes in v4: -- delete DPU_DSC_HW_REV_1_1 -- delete off and used real register name directly Changes in v7: -- replace offset with sblk->enc.base -- replace ss with slice Changes in v8: -- fixed checkpatch warning Changes in v9: -- replaced __dsc_calc_ob_max_addr() with __dsc_calc_output_buf_max_addr() -- replaced variable num_ss with num_softslice -- remove inline from function declaration changes in v10: -- rewording text of changes in v9 -- replace DPU_DSC_NATIVE_422_EN with DPU_DSC_NATIVE_42x_EN -- replace drm_dsc_calculate_flatness_det_thresh() with drm_dsc_flatness_det_thresh() Signed-off-by: Kuogee Hsieh <quic_khsieh@quicinc.com> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Reviewed-by: Marijn Suijten <marijn.suijten@somainline.org> Patchwork: https://patchwork.freedesktop.org/patch/539500/ Link: https://lore.kernel.org/r/1685036458-22683-7-git-send-email-quic_khsieh@quicinc.com Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>
