drm/exynos/fbdev: do not skip fbdev init if there are no connectors

2018-11-05T07:37:24+00:00

Since connectors can be created dynamically, fbdev should be initialized even if there are no connectors at the moment. Otherwise fbdev will not be created even after connector's appearance. The patch fixes lack of fbdev on rinato and trats boards.

drm/exynos/dsi: register connector if it is created after drm bind

2018-11-05T07:37:24+00:00

DSI device can be attached after DRM device is registered. In such case newly created connector must be registered by exynos_dsi. The patch fixes exynos_drm on rinato and trats boards.

Revert "drm/exynos/decon5433: implement frame counter"

2018-11-05T07:37:24+00:00

This reverts commit 0586feba322e1de05075700eb4b835c8b683e62b This patch makes it to need get_vblank_counter callback in crtc to get frame counter from decon driver. However, drm_dev->max_vblank_count is a member unique to vendor's DRM driver but in case of ARM DRM, some CRTC devices don't provide the frame counter value. As a result, this patch made extension and clone mode not working. Instead of this patch, we may need separated max_vblank_count which belongs to each CRTC device, or need to implement frame counter emulation for them who don't support HW frame counter.

drm/exynos: checking for NULL instead of IS_ERR()

2018-11-05T07:37:24+00:00

The of_drm_find_panel() function returns error pointers and never NULL but we the driver assumes that ->panel is NULL when it's not present. Fixes: 6afb7721e2a0 ("drm/exynos: move connector creation to attach callback") Signed-off-by: Dan Carpenter Signed-off-by: Inki Dae

drm/exynos: mixer: Make plane alpha configurable

2018-10-01T02:49:59+00:00

The mixer hardware supports variable plane alpha. Currently planes are opaque, make this configurable. Tested on Odroid-U3 with Exynos 4412 CPU, kernel next-20180913 using modetest. Signed-off-by: Christoph Manszewski Signed-off-by: Inki Dae

drm/exynos: mixer: Make pixel blend mode configurable

drm/exynos: Use selected dma_dev default iommu domain instead of a fake one

2018-10-01T00:25:31+00:00

Instead of allocating a fake IOMMU domain for all Exynos DRM components, simply reuse the default IOMMU domain of the already selected DMA device. This allows some design changes in IOMMU framework without breaking IOMMU support in Exynos DRM. Signed-off-by: Marek Szyprowski Reviewed-by: Robin Murphy Signed-off-by: Inki Dae
