2016-11-02dt-bindings: display: display-timing: Add property to configure sync drive edgePeter Ujfalusi
There are display panels which demands that the sync signal is driven on different edge than the pixel data. With the syncclk-active property we can specify the clk edge to be used to drive the sync signal. When the property is missing it indicates that the sync is driven on the same edge as the pixel data.

2016-11-02drm/omap: print error instead of WARN() if plane setup failsTomi Valkeinen
omap_plane_atomic_update() does WARN_ON() if dispc rejects the given plane config. Change that to dev_err() to lessen the possible spam. To fix this correctly, the plane setup needs much more work by creating a check function for dispc setup, so that we could reliably check the config in atomic_check, instead of only noticing the problem when programming dispc.

2016-11-02drm/omap: cleanup omap_plane_atomic_check()Tomi Valkeinen

2016-11-02drm/omap: fix plane check when crtc is disabledTomi Valkeinen
I sometimes see: [drm:drm_framebuffer_remove [drm]] *ERROR* failed to reset crtc ed2a6c00 when fb was deleted: -22 which comes from drm_framebuffer_remove() when it's disabling the crtc with zeroed drm_mode_set. The problem in omap_plane_atomic_check() is that it will use those zeroed fields to verify if the setup is correct. This patch makes omap_plane_atomic_check() return 0 if the crtc is disabled.

2016-11-01gpio/mvebu: Use irq_domain_add_linearJason Gunthorpe
This fixes the irq allocation in this driver to not print: irq: Cannot allocate irq_descs @ IRQ34, assuming pre-allocated irq: Cannot allocate irq_descs @ IRQ66, assuming pre-allocated Which happens because the driver already called irq_alloc_descs() and so the change to use irq_domain_add_simple resulted in calling irq_alloc_descs() twice. Modernize the irq allocation in this driver to use the irq_domain_add_linear flow directly and eliminate the use of irq_domain_add_simple/legacy Fixes: ce931f571b6d ("gpio/mvebu: convert to use irq_domain_add_simple()") Signed-off-by: Jason Gunthorpe <jgunthorpe@obsidianresearch.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2016-11-01drm/i915: Allow shrinking of userptr objects once againTvrtko Ursulin
Commit 1bec9b0bda3d ("drm/i915/shrinker: Only shmemfs objects are backed by swap") stopped considering the userptr objects in shrinker callbacks. Restore that so idle userptr objects can be discarded in order to free up memory. One change further to what was introduced in 1bec9b0bda3d is to start considering userptr objects in oom but that should also be a correct thing to do. v2: Introduce I915_GEM_OBJECT_IS_SHRINKABLE.

2016-11-01drm/i915: Export a function to flush the context upon pinningChris Wilson
For legacy contexts we employ an optimisation to only flush the context when binding into the global GTT. This avoids stalling on the GPU when reloading an active context. Wrap this detail up into a helper and export it for a potential third user. (Longer term, context pinning needs to be reworked as the current handling of switch context pins too late and so risks eviction and corrupting the request. Plans, plans, plans.) v2: Expand the comment explaining the optimisation for avoiding the stall on active contexts.

2016-11-01drm/i915/gen9+: Use the watermarks from crtc_state for everything, v2.Maarten Lankhorst
There's no need to keep a duplicate skl_pipe_wm around any more, everything can be discovered from crtc_state, which we pass around correctly now even in case of plane disable. The copy in intel_crtc->wm.skl.active is equal to crtc_state->wm.skl.optimal after the atomic commit completes. It's useful for two-step watermark programming, but not required for gen9+ which does it in a single step. We can pull the old allocation from old_crtc_state.

It's only used in one function, and can be calculated without caching it in the global struct by using drm_atomic_crtc_state_for_each_plane_state. There are loops over all planes, including planes that don't exist. This is harmless, because data_rate will always be 0 for them and we never program them when updating watermarks.
