drm/exynos: atomic check only enabled crtc states

2015-12-19T16:39:10Z

Since atomic check is called also for disabled crtcs it should skip mode checking as it can be uninitialized. The patch fixes it. Signed-off-by: Andrzej Hajda Suggested-by: Daniel Vetter Tested-by: Javier Martinez Canillas Signed-off-by: Inki Dae

drm/exynos/gem: remove DMA-mapping hacks used for constructing page array

2015-11-03T02:46:39Z

Exynos GEM objects contains an array of pointers to the pages, which the allocated buffer consists of. Till now the code used some hacks (like relying on DMA-mapping internal structures or using ARM-specific dma_to_pfn helper) to build this array. This patch fixes this by adding proper call to dma_get_sgtable_attrs() and using the acquired scatter-list to construct needed array. This approach is more portable (work also for ARM64) and finally fixes the layering violation that was present in this code. Signed-off-by: Marek Szyprowski Signed-off-by: Inki Dae

drm/exynos: simplify Kconfig component names

2015-11-03T02:46:38Z

Many Exynos DRM sub-options mentions Exynos DRM in their titles. It is redundant and can be safely shortened. The patch additionally makes some entries more descriptive. Signed-off-by: Andrzej Hajda Signed-off-by: Inki Dae

drm/exynos: re-arrange Kconfig entries

2015-11-03T02:46:38Z

Exynos DRM driver have quite big number of components and options. The patch re-arranges them into three logical groups: - CRTCs, - Encoders and Bridges, - Sub-drivers. It should make driver options more clear. Signed-off-by: Andrzej Hajda Signed-off-by: Inki Dae

drm/exynos: abstract out common dependency

2015-11-03T02:46:38Z

All options depends on DRM_EXYNOS so it can be moved to enclosing if clause. Signed-off-by: Andrzej Hajda Signed-off-by: Inki Dae

drm/exynos: separate Mixer and HDMI drivers

2015-11-03T02:46:38Z

Latest Exynos SoCs does not have Mixer IP, but they still have HDMI IP. Their drivers should be configurable separately. Signed-off-by: Andrzej Hajda Signed-off-by: Inki Dae

drm/exynos/mixer: replace direct cross-driver call with drm mode validation

2015-11-03T02:46:38Z

HDMI driver called directly function from MIXER driver to invalidate modes not supported by MIXER. The patch replaces the hack with proper .atomic_check callback. Signed-off-by: Andrzej Hajda Signed-off-by: Inki Dae

drm/exynos: add atomic_check callback to exynos_crtc

2015-11-03T02:46:37Z

Some CRTCs needs mode validation, this patch adds neccessary callback to Exynos DRM framework. It is called from DRM core via atomic_check helper for drm_crtc. Signed-off-by: Andrzej Hajda Signed-off-by: Inki Dae

drm/exynos/decon5433: add support for DECON-TV

2015-11-03T02:46:37Z

DECON-TV IP is responsible for generating video stream which is transferred to HDMI IP. It is almost fully compatible with DECON IP. The patch is based on initial work of Hyungwon Hwang. Signed-off-by: Andrzej Hajda Signed-off-by: Inki Dae
