[Intel-gfx] [PATCH] drm/i915: Unlock PPS registers after GPU reset

2016-09-14 Thread Imre Deak

Reapply the PPS register unlock workaround after GPU reset on platforms where the reset clobbers the display HW state. This at least gets rid of the related WARN during LVDS encoder enabling on PNV. Fixes: ed6143b8f75 ("drm/i915/lvds: Restore initial HW state during encoder enabling")
