2015-03-19drm/radeon: add DisplayPort MST support (v2)Dave Airlie
This adds initial DP 1.2 MST support to radeon, on CAYMAN and up in theory. This is off by default. v2: agd5f: - add UNIPHY3 offsets - move atom cmd table code into atombios_encoders.c - whitespace cleanup - replace some magic numbers with proper defines Signed-off-by: Dave Airlie <airlied@redhat.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2015-03-19drm/radeon: improve encoder picking functions (v2)Dave Airlie
For MST we need to be able to pick front end encoders separate from backend, but only for MST, so we need to make the encoder picking interface smarter. v2: agd5f: squash in: drm/radeon: release digital encoder before asking for new one Reported-by: Dieter Nützel <Dieter@nuetzel-hh.de> Signed-off-by: Dave Airlie <airlied@redhat.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2015-03-19drm/dp_mst: add a function to retrieve vcpi slotsDave Airlie
radeon requires this to get the slots for later filling out a table on every transition. Signed-off-by: Dave Airlie <airlied@redhat.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2015-03-19drm/radeon: program auxch directly (v2)Dave Airlie
The atombios tables have an unfortunate restriction on only being able to write 12 bytes, MST really wants 16-bytes here, and since the hw can do it, we should just write directly to it. This uses a module option to allow for it now, and maybe we should provide the old code as a fallback for a while. v2: (agd5f) - move registers to a proper register header - only enable on DCE5+ - enable by default on DCE5+ - Switch pad to aux mode before using it - reformat instance handling to better match the rest of the driver Signed-off-by: Dave Airlie <airlied@redhat.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2015-03-19drm/radeon: add an output_csc propertyAlex Deucher
This adds the drm property for output csc (e.g., transform of output display colorspace). Currently only common ones (TV RGB, BT.601, BT.709) are supported, but bypass and tv rgb are really the only useful ones at the moment. Additionally we could expose a user adjustable matrix in the future. This commit just adds the property. The hw support will be added in subsequent patches. bug: https://bugs.freedesktop.org/show_bug.cgi?id=83226 Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2015-03-19drm: adv7511: Refactor power managementLaurent Pinchart
Remove the internal dependency on DPMS mode for power management by using a by a powered state boolean instead, and use the new power off handler at probe time. This ensure that the regmap cache is properly marked as dirty when the device is probed, and the registers properly synced during the first power up. As a side effect this removes the initialization of current_edid_segment at probe time, as the field will be initialized when the device is powered on, at the latest right before reading EDID data.

2015-03-19drm: adv7511: Fix nested sleep when reading EDIDLaurent Pinchart
The EDID read code waits for the read completion interrupt to occur using wait_event_interruptible(). The condition passed to the macro reads I2C registers. This results in sleeping with the task state set to TASK_INTERRUPTIBLE, triggering a WARN_ON() introduced in commit 8eb23b9f35aae ("sched: Debug nested sleeps"). Fix this by reworking the EDID read code. Instead of checking whether the read is complete through I2C reads, handle the interrupt registers in the interrupt handler and update a new edid_read flag accordingly. As a side effect both the IRQ and polling code paths now process the interrupt sources through the same code path, simplifying the code.

2015-03-19drm: rcar-du: Fix framebuffer reference leak through plane stateLaurent Pinchart
Plane state duplication takes a reference to the framebuffer stored in the state, but state destroy doesn't release it. This causes a reference leak. Fix it. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

2015-03-19Merge branch 'exynos-drm-fixes' of ↵Dave Airlie
git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-fixes Some urgent regression fixes to booting failures Exynos DRM occured. Summary: - Fix two urgent null pointer dereference bugs in case of enabling or disabling IOMMU. There was two cases to these issues. One is that plane->crtc is accessed by exynos_disable_plane() when device tree binding is broken so device driver tries to release, which means that the mode set operation isn't invoked yet so plane->crtc is still NULL and exynos_disable_plane() will access NULL pointer. This issue is fixed by checking if the plane->crtc is NULL or not in exynos_disable_plane() Other is that fimd_wait_for_vblank() is called to avoid from page fault with IOMMU before the ctx object is created. At this time, fimd_wait_for_vblank() tries to access ctx->crtc but the ctx->crtc is still NULL because exynos_drm_crtc_create() isn't called yet. This issue is fixed by creating a crtc object and setting it to ctx->crtc prior to fimd_wait_for_vblank() call. For more details, you can refer to below an e-mail thread, http://www.spinics.net/lists/linux-samsung-soc/msg42436.html - Remove unnecessary file not used and fix trivial issues. * 'exynos-drm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos: drm/exynos: fix the initialization order in FIMD drm/exynos: fix typo config name correctly. drm/exynos: Check for NULL dereference of crtc drm/exynos: IS_ERR() vs NULL bug drm/exynos: remove unused files
