drm/dsc: Define Rate Control values that do not change over configurations
DSC has some Rate Control values that remain constant across all configurations. These are as per the DSC standard. v3: * Define them in drm_dsc.h as they are DSC constants (Manasi) v2: * Add DP_DSC_ prefix (Jani Nikula) Cc: [email protected] Cc: Manasi Navare <[email protected]> Cc: Jani Nikula <[email protected]> Cc: Ville Syrjala <[email protected]> Cc: Gaurav K Singh <[email protected]> Cc: Harry Wentland <[email protected]> Signed-off-by: Srivatsa, Anusha <[email protected]> Signed-off-by: Manasi Navare <[email protected]> Reviewed-by: Manasi Navare <[email protected]> Acked-by: Sean Paul <[email protected]> (For merging through drm-intel) Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
