drm/exynos/decon5433: set STANDALONE_UPDATE_F on output enablement

2017-01-20T07:17:12+00:00

DECON_TV requires STANDALONE_UPDATE after output enabling, otherwise it does not start. This change is neutral for DECON. Signed-off-by: Andrzej Hajda Signed-off-by: Inki Dae

drm/exynos/decon5433: fix CMU programming

2017-01-20T07:02:28+00:00

DECON_CMU register has reserved bits which should not be zeroed, otherwise IP can behave strangely and cause IOMMU faults. Signed-off-by: Andrzej Hajda Signed-off-by: Inki Dae

drm/exynos/decon5433: do not disable video after reset

2017-01-20T07:00:20+00:00

decon_commit is called just after reset so video is disabled anyway. Signed-off-by: Andrzej Hajda Signed-off-by: Inki Dae

drm/exynos/decon5433: set STANDALONE_UPDATE_F also if planes are disabled

2017-01-13T09:22:51+00:00

STANDALONE_UPDATE_F should be set if something changed in plane configurations, including plane disable. The patch fixes page-faults bugs, caused by decon still using framebuffers of disabled planes. v2: fixed clear-bit code (Thx Marek) v3: use test_and_clear_bit (Thx Joonyoung) Signed-off-by: Andrzej Hajda Tested-by: Joonyoung Shim Signed-off-by: Inki Dae

drm/exynos/decon5433: update shadow registers iff there are active windows

2017-01-13T09:01:20+00:00

Improper usage of DECON_UPDATE register leads to subtle errors. If it set in decon_commit when there are no active windows it results in slow registry updates - all subsequent shadow registry updates takes more than full vblank. On the other side if it is not set when there are active windows it results in garbage on the screen after suspend/resume of FB console. The patch hopefully fixes it.

mm: use vmf->address instead of of vmf->virtual_address

2016-12-15T00:04:09+00:00

Every single user of vmf->virtual_address typed that entry to unsigned long before doing anything with it so the type of virtual_address does not really provide us any additional safety. Just use masked vmf->address which already has the appropriate type. Link: http://lkml.kernel.org/r/1479460644-25076-3-git-send-email-jack@suse.cz Signed-off-by: Jan Kara Acked-by: Kirill A.

drm/exynos: Use VIDEO_SAMSUNG_EXYNOS_GSC=n as GSC Kconfig dependency

2016-12-05T13:08:59+00:00

Commit aeefb36832e5 ("drm/exynos: gsc: add device tree support and remove usage of static mappings") made the DRM_EXYNOS_GSC Kconfig symbol to only be selectable if the exynos-gsc V4L2 driver isn't enabled, since both use the same HW IP block. But added the dependency as depends on !VIDEO_SAMSUNG_EXYNOS_GSC which is not correct since Kconfig expressions are not boolean but tristate. So it will only evaluate to 'n' if VIDEO_SAMSUNG_EXYNOS_GSC=y but will evaluate to 'm' if VIDEO_SAMSUNG_EXYNOS_GSC=m. This means that both the V4L2 and DRM drivers can be enabled if the former is enabled as a module, which isn't what we want since otherwise 2 drivers could attempt to use the hardware at the same time.
