Subject:  [PATCH v3 3/3] drm/i915/display/psr: Do full fetch when
handling biplanar formats

From: Gwan-gyeong Mun <gwan-gyeong.mun@xxxxxxxxx>

We are still missing the PSR2 selective fetch handling of biplanar formats but
until proper handle is added we can workaround it by doing full frames fetch
when state has biplanar formats.

We need the second check because an update in a regular format could
intersect with a biplanar plane that was not initialy part of the atomic commit.

Code comment can be added here why we need this check again in same function.
Enabling full frame update is fine for me for planar format but not sure we need the 2nd check.

That's right, we don't need to set this code here because we set full_update above when " new_plane_state->hw.fb->format->is_yuv" is true.

I will update this in the next version.

Thanks, Animesh.
