This patch resolves page fault issue of Mixer when disabled. The SFRs of VP and Mixer are updated by Vertical Sync of Timing generator which is a part of HDMI so the sequence to disable TV Subsystem should be as following: VP -> Mixer -> HDMI For this, this patch disables Mixer and VP (if used) prior to disabling HDMI.

This patch makes sure that exynos drm framework handles deferred probe case correctly. Sub drivers could be probed before resources, clock, regulator, phy or panel, are ready for them so we should make sure that exynos drm core waits until all resources are ready and sub drivers are probed correctly. Chagelog v2: - Make sure that exynos drm core tries to bind sub drivers only in case that they have a pair: crtc and encoder/connector components should be a pair. - Remove unnecessary patch: drm/exynos: mipi-dsi: consider panel driver-deferred probe - Return error type correctly.

Exynos drm hdmi driver used to get dummy hdmiphy clock to control the PMU bit for hdmiphy. This bit needs to be set before setting any resolution to hdmi hardware. This was handled using dummy hdmiphy clock which is removed here. PMU is already defined as system controller for exynos SoCs. Hdmi driver is modified to control the phy enable bit inside PMU using regmap interfaces. Devicetree binding document for hdmi is also updated.

This patch trims exynos_drm_hdmi out of the driver. The reason it existed in the first place was to make up for the mixture of display/overlay/manager ops being spread across hdmi and mixer.
