[Intel-gfx] [PATCH 03/10] drm/i915: Add support for asynchronous display power disabling

2019-05-02 Thread Imre Deak
By disabling a power domain asynchronously we can restrict holding a reference on that power domain to the actual code sequence that requires the power to be on for the HW access it's doing, by also avoiding unneeded on-off-on togglings of the power domain (since the disabling happens with a delay)
