drm/i915/dp: Add DSC params and DSC config to intel_crtc_state
Basic DSC parameters and DSC configuration data needs to be computed for each of the requested mode during atomic check. This is required since for certain modes, valid DSC parameters and config data might not be computed in which case compression cannot be enabled for that mode. For that reason we need to add these params and config structure to the intel_crtc_state so that if valid this state information can directly be used while enabling DSC in atomic commit. v2: * Rebase on drm-tip (Manasi) Cc: Gaurav K Singh <gaurav.k.singh@intel.com> Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: Ville Syrjala <ville.syrjala@linux.intel.com> Cc: Anusha Srivatsa <anusha.srivatsa@intel.com> Signed-off-by: Manasi Navare <manasi.d.navare@intel.com> Reviewed-by: Anusha Srivatsa <anusha.srivatsa@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20181128202628.20238-1-manasi.d.navare@intel.com
