>Subject: [PATCH v2 11/23] 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.
