Commit Message

Marek Szyprowski June 11, 2018, 12:25 p.m.
Add calls to pm_runtime_force_{suspend,resume} as SYSTEM_SLEEP_PM_OPS for
all drivers for the real Exynos DRM hardware modules. This ensures that
the resources will be released for the system PM suspend/resume cycle.
Exynos DRM core already takes care of suspending the whole display pipeline
before PM callbacks of the real devices are called.
