From 7e915746de03e0e62d58491f22805cc5a80a581a Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Mon, 11 Jun 2018 14:25:00 +0200 Subject: drm/exynos: Ensure suspended runtime PM state during system suspend 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.
