2019-06-27drm/exynos: drop drmP.h usageSam Ravnborg
Drop use of the deprecated drmP.h file. Replace with forwards / externals as appropriate. While touching the list of include files divide them up in blocks and sort them. v3: - fix build errors in exynos_drm_g2d.c (Inki Dae) The exynos_drm_g2d.c file is not built in the standard configurations and was therefore missed.

Exynos DRM drivers should work with and without IOMMU. Providing common API generic to both scenarios should make code cleaner and allow further code improvements.

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.

Instead I did the unsafe way, and tried to look over the entire diff to spot if any dangerous expressions were produced. I didn't see any. There are some cases where previously the code did X*bpp/8, so the division happened after the multiplication.

2015-06-20drm/exynos: remove chained calls to enableJoonyoung Shim
With atomic modesetting all the control for CRTC, Planes, Encoders and Connectors should come from DRM core, so the driver is not allowed to enable or disable planes from inside the crtc_enable()/disable() call. But it needs to disable planes with crtc_disable in exynos driver internally. Because crtc is disabled before plane is disabled, it means plane_disable just returns without any register changes, then we cannot be sure setting register to disable plane when crtc is disable. This patch removes this chainned calls to enable plane from exynos hw drivers code letting only DRM core touch planes except to disable plane. Also it leads eliminable enabled and resume of struct exynos_drm_plane.

2015-06-20drm/exynos: fix broken component binding in case of multiple pipelinesAndrzej Hajda
In case there are multiple pipelines and deferred probe occurs, only components of the first pipeline were bound. As a result only one pipeline was available. The main cause of this issue was dynamic generation of component match table - every component driver during probe registered itself on helper list, if there was at least one pipeline present on this list component match table were created without deferred components. This patch removes this helper list, instead it creates match table from existing devices requiring exynos_drm KMS drivers. This way match table do not depend on probe/deferral order and contains all KMS components. As a side effect patch makes the code cleaner and significantly smaller.
