Hi Inki, This patchset removes hacky mode validation in Mixer driver by adding atomic_check callback to exynos_crtc and replacing direct function call with DRM framework validation. As a result HDMI driver does not depend anymore on MIXER driver and both drivers can be selected with different Kconfig options, it is usefull especially for latests SoCs which do have HDMI IP but do not have MIXER IP. Additionally patchset performs small Kconfig refactoring. Krzysztof could you look at exynos_defconfig patch. Maybe it would be good to merge it before next patch to allow full bi-sectability :) Regards Andrzej Andrzej Hajda (7): drm/exynos: add atomic_check callback to exynos_crtc drm/exynos/mixer: replace direct cross-driver call with drm mode validation ARM: exynos_defconfig: enable Exynos DRM Mixer driver drm/exynos: separate Mixer and HDMI drivers drm/exynos: abstract out common dependency drm/exynos: re-arrange Kconfig entries drm/exynos: simplify Kconfig component names arch/arm/configs/exynos_defconfig | 1 + drivers/gpu/drm/exynos/Kconfig | 75 +++++++++++++++++++------------- drivers/gpu/drm/exynos/Makefile | 3 +- drivers/gpu/drm/exynos/exynos_drm_crtc.c | 12 +++++ drivers/gpu/drm/exynos/exynos_drm_drv.c | 4 +- drivers/gpu/drm/exynos/exynos_drm_drv.h | 3 ++ drivers/gpu/drm/exynos/exynos_hdmi.c | 5 --- drivers/gpu/drm/exynos/exynos_mixer.c | 6 ++- drivers/gpu/drm/exynos/exynos_mixer.h | 20 --------- 9 files changed, 69 insertions(+), 60 deletions(-) delete mode 100644 drivers/gpu/drm/exynos/exynos_mixer.h -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
