Merge branch 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next
Summary: - Support for pipeline clock between KMS drivers. . Exynos SoC is required to control clocks across KMS drivers according to Exynos SoC version. So this patch refactos some relevant codes and provides generic solution for it. - Add Exynos5433 SoC support to HDMI parts - HDMI and DECON-TV. - Add HW trigger mode support to CRTC drivers. . In case of using i80 Panel, some Exynos SoC supports HW trigger mode so this patch makes trigger mode - HW or SW trigger - to be set according to SoC version properly. - And some cleanups and regression fixups. * 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos: (39 commits) drm/exynos: clean up register definions for fimd and decon drm/exynos: decon: clean up interface type drm/exynos: fimd: add HW trigger support drm/exynos: clean up wait_for_vblank drm/exynos: mixer: use generic of_device_get_match_data helper drm/exynos: mixer: remove support for non-dt platforms drm/exynos: hdmi: use generic of_device_get_match_data helper drm/exynos: rotator: use generic of_device_get_match_data helper drm/exynos: fimd: use generic of_device_get_match_data helper drm/exynos: dsi: use generic of_device_get_match_data helper drm/exynos: exynos5433_decon: use generic of_device_get_match_data helper drm/exynos: convert clock_enable crtc callback to pipeline clock drm/exynos/mixer: enable HDMI-PHY before configuring MIXER drm/exynos/decon5433: enable HDMI-PHY before configuring DECON drm/exynos: add support for pipeline clock to the framework drm/exynos: add helper to get crtc from pipe drm/exynos/decon5433: do not protect window in plane disable drm/exynos/decon5433: reset decon on start drm/exynos/decon5433: fix DECON standalone update drm/exynos/hdmi: remove registry dump ...
