Re: [PATCH 2/2] drm/i915: eDP DRRS limited to only one panel at a time

Hi Siva,

Since the same structure will be used to implement DRRS on DSI also we have placed it at i915_dev_priv.
I am working on the RFC for the DRRS on DSI.

since drrs struct is used primarily in intel_dp.c file alone can it be moved to intel_dp ?

In case of multiple eDP panels, only one can have
the DRRS enabled on it.

In future eDP DRRS will be extended for multiple panels.
