[PATCH 15/15] drm/i915: Enable PSR for Baytrail and Braswell.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch is the last in series of VLV/CHV PSR,
that finnaly enable psr by adding it to HAS_PSR
and calling the proper enable and disable
functions on the right places.

Although it is still disabled by default.

v2: Rebase over intel_psr and merge Durgadoss's fixes.
