[Intel-gfx] [PATCH 4/4] drm/i915: Add Baytrail PSR Support.

2014-01-28 Thread Rodrigo Vivi
This patch adds PSR Support to Baytrail. Baytrail cannot easily detect screen updates and force PSR exit. So we inactivate it on {busy_ioctl, set_domain, sw_finish and mark_busy and update to enable it back on next display mark_idle. v2: Also inactivate PSR on cursor update. v3: Inactivate PSR on
