drm/dsc: Modify DRM helper to return complete DSC color depth capabilities
DSC DPCD color depth register advertises its color depth capabilities by setting each of the bits that corresponding to a specific color depth. This patch defines those specific color depths and adds a helper to return an array of color depth capabilities. v2: * Simplify the logic (Ville) Signed-off-by: Manasi Navare <manasi.d.navare@intel.com> Cc: Ville Syrjala <ville.syrjala@linux.intel.com> Acked-by: Sean Paul <seanpaul@chromium.org> (For merging through drm-intel) Reviewed-by: Ville Syrjala <ville.syrjala@linux.intel.com> Reviewed-by: Anusha Srivatsa <anusha.srivatsa@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20181127214125.17658-1-manasi.d.navare@intel.com
