Sure, will update this.

Ok, have taken care of it and sent out the next version.
Thanks Ville for the feedback.

Actually vlv/chv might have it since the vlv video DIP was supposedly
ripped from ibx. So potentially we could just enable this for all ilk+.
But that would require actual testing, so hsw+ seems like good enough
for now.

CHV does not have this at all, and HSW/BDW don't have it on transcoder EDP.

Also if we're going to attach this unconditionally then we should stop
attaching it again in the LSPCON init path. Or we should skip this one
when LSPCON is present.

[Intel-gfx] [PATCH] drm/i915/display: Extend DP HDR support to hsw+

2022-03-23 Thread Uma Shankar
HSW+ platforms are able to send out HDR Metadata SDP DIP
packet as GMP. Hence, extending the support for HDR on DP
encoders for the same.
