This patch defines the DP DSC receiver capability size that gives total number of DP DSC DPCD registers. This also adds a missing SHIFT define missed in the commit id (ab6a46ea6842ce "Add DPCD definitions for DP 1.4 DSC feature") v2: * Missed the SHIFT define that I mentioned in the message Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: Ville Syrjala <ville.syrjala@linux.intel.com> Cc: Anusha Srivatsa <anusha.srivatsa@intel.com> Cc: dri-devel@lists.freedesktop.org Signed-off-by: Manasi Navare <manasi.d.navare@intel.com> --- include/drm/drm_dp_helper.h | 4 ++++ 1 file changed, 4 insertions(+)
