2015-05-27drm/tilcdc: Add DRM_TILCDC_SLAVE_COMPAT for ti,tilcdc,slave binding supportJyri Sarha
Adds a CONFIG_DRM_TILCDC_SLAVE_COMPAT module for "ti,tilcdc,slave" node conversion. The implementation is in tilcdc_slave_compat.c and it uses tilcdc_slave_compat.dts as a basis for creating a DTS overlay. The DTS overlay adds an external tda998x encoder to tilcdc that corresponds to the old tda998x based slave encoder.

2015-05-27drm/tilcdc: use pm_runtime_irq_safe()Tomi Valkeinen
tilcdc calls runtime PM get/put functions everywhere. Some of those places will be called in irq context, crashing the driver. As a quick fix, use pm_runtime_irq_safe() for tilcdc. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Signed-off-by: Jyri Sarha <jsarha@ti.com>
2015-05-27drm/tilcdc: Add support for external tda998x encoderJyri Sarha
Add support for an external compontised DRM encoder. The external encoder can be connected to tilcdc trough device tree graph binding. The binding document for tilcdc has been updated. The current implementation supports only tda998x encoder. To be able to filter out the unsupported video modes the tilcdc driver needs to hijack the external connectors helper functions. The tilcdc installes new helper functions that are otherwise identical to orignals, but the mode_valid() call-back check the mode first localy, before calling the original call-back. The tilcdc dirver restores the original helper functions before it is unbound from the external device. I got the idea and some lines of code from Jean-Francois Moine's "drm/tilcdc: Change the interface with the tda998x driver"-patch.

2015-05-26drm/i915: Use spinlocks for checking when to waitboostChris Wilson
In commit 1854d5ca0dd7a9fc11243ff220a3e93fce2b4d3e Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Tue Apr 7 16:20:32 2015 +0100 drm/i915: Deminish contribution of wait-boosting from clients we removed an atomic timer based check for allowing waitboosting and moved it below the mutex taken during RPS. However, that mutex can be held for long periods of time on Vallyview/Cherryview as communication with the PCU is slow. As clients may frequently wait for results (e.g. such as tranform feedback) we introduced contention between the client and the RPS worker. We can take advantage of the RPS worker, by switching the wait boost decision to use spin locks and defer the actual reclocking to the worker. Fixes a regression of up to 45% on Baytrail and Baswell! v2 (Daniel): - Use max_freq_softlimit instead of the not-yet-merged boost frequency. - Don't inject a fake irq into the boost work, instead treat client_boost as just another legit waker. v3: Drop the now unused mask (Chris).

2015-05-26drm/vgem: drop DRIVER_PRIME (v2)Rob Clark
For actual sharing of buffers with other drivers (ie. actual hardware) we'll need to pimp things out a bit better to deal w/ caching, multiple memory domains, etc. See thread: http://lists.freedesktop.org/archives/dri-devel/2015-May/083160.html But for the llvmpipe use-case this isn't a problem. Nor do we really need prime/dri3 (dri2 is sufficient). So until the other issues are sorted lets remove DRIVER_PRIME. v2: also drop the dead code [airlied: Okay I'm convinced this API could have a lot of use cases that are really really bad, yes the upload use case is valid however that isn't the only use case enabled, and if we allow all the other use cases, people will start to (ab)use them, and then they'll be ABI and my life will get worse, so disable PRIME for now] Acked-by: Thomas Hellstrom <thellstrom@vmware.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Rob Clark <robdclark@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2015-05-25drm: rcar-du: Split planes pre-association 4/4 between CRTCsLaurent Pinchart
If we have more than one CRTCs in a group pre-associate planes 0-3 with CRTC 0 and planes 4-7 with CRTC 1 to minimize flicker occurring when the association is changed.

2015-05-25drm: rcar-du: Store the number of CRTCs per group in the group structureLaurent Pinchart

2015-05-25drm: rcar-du: Consider plane to CRTC associations in the plane allocatorLaurent Pinchart
Hardware planes are driven by the timing generator of the CRTC they are associated to. Changing the association requires restarting the CRTC group that the plane belongs to, resulting in flicker on the other CRTC. To avoid flicker as much as possible, try to allocate planes first from the free planes already associated with the target CRTC. If allocation fails then fall back to allocation from all free planes.

2015-05-25drm: rcar-du: Keep plane to CRTC associations when disabling a planeLaurent Pinchart
