2016-06-20drm: rcar-du: error message is not needed for drm_vblank_init()Kuninori Morimoto
The only reason drm_vblank_init() could return an error at the moment is a kcalloc() failure. So we can remove current error message completely.

2016-06-20rcar-du: add/rename DEFR6 TCON bitsSergei Shtylyov
The TCNE2 bit of the DEFR6 register was renamed to TCNE1 in the R-Car gen2 manuals -- which makes more sense as that bit controls whether DU1, not DU2 is connected to TCON. While at it, add the TCNE0 bit which controls whether DU0 is connected to TCON. Based on the large patch by Andrey Gusakov <andrey.gusakov@cogentembedded.com>.

git://anongit.freedesktop.org/drm-intel into drm-next - best_encoder cleanup from Boris. - drm_simple_display_pipe helpers from Noralf. Looks really neat imo, and there's 2-3 in-flight drivers which look like they could/should use it. Anyway, with this we have now helpers and everything in place to write drivers for simple hw with fewer complexity in the driver than what fbdev would need. That was the last complaint I've heard from embedded folks after we made atomic happen. Mission accomplished! - nonblocking commit helpers for atomic, plus a bunch of driver patches for that. - Prep patch from Laurent for cleaned up pixel format functions. - More of Gustavo's cleanup for drm vblank functions. - and a few oddball things in between Plus the merge of docs-next to prep the docbook->sphinx conversion as discussed.

2016-06-15drm/atomic-helpers: Stall on the right commitDaniel Vetter
stall_checks carefully picked out the right commit to stall on, then promptly used the wrong variable. Due to the break in the next loop iteration this could be the 3rd commit, or if the list only has 2 entries commit would now point into the struct drm_crtc itself, at some offset. Hilarity eventually ensues. For added safety, also break right away instead of iterating once more, but the real fix is waiting on stall_commit instead of commit.

2016-06-10drm: arc: Rely on the default ->best_encoder() behaviorBoris Brezillon
We have a 1:1 relationship between connectors and encoders and the driver is relying on the atomic helpers: we can drop the custom ->best_encoder(), and let the core call drm_atomic_helper_best_encoder() for us.

2016-06-10drm: Fix comment making reference to non-existing functionLiviu Dudau
Documentation for drm_atomic_crtc_for_each_plane() makes reference to a function called drm_crtc_for_each_pending_plane(). I've guessed that the actual function name is drm_atomic_crtc_state_for_each_plane() as that matches best the intent of the comment.

2016-06-10drm/rockchip: Resume DP earlyTomeu Vizoso
The DP needs to have resumed once the DRM driver calls drm_atomic_helper_resume, otherwise the DP clock is still disabled when the DRM core enables the DP bridge. Would be nice to use device_pm_wait_for_dev to synchronize these devices, but the DRM device doesn't know what specific implementation this bridge has.

2016-06-10drm/rockchip: Use atomic PM helpersTomeu Vizoso
This driver was still using the old legacy helpers and that caused a few NULL dereferences when trying to call empty callbacks.

2016-06-10drm/rockchip: convert to helper nonblocking atomic commitDaniel Vetter
With the various bits fixed rockchip now has an atomic compliant handling/signalling of crtc_state->event, which means we can just switch over to the new nonblocking helpers and remove some code. v2: Fixes from Tomeu. v3: Send out vblank events correctly when shutting down a crtc for good. This is part of the atomic interface contract. v4: Properly protect vop->event. v5: Add more WARN_ON to check vop->event isn't clobbered.

2016-06-10drm/rockchip: Fix crtc_state->event signallingDaniel Vetter
It's not permissible to look at plane->state from interrupt context, since doing that would need the irq handler to acquire the plane->mutex lock. The other problem is that if we pipeline updates using the new nonblocking atomic helpers new state gets commit before the irq handler fires, resulting in a lost event. Fix both issues by caching the necessary values in vop_win, protected by dev->event_lock.

2016-06-10drm/rockchip: Disarm vop->is_enabledDaniel Vetter
With atomic helpers there's no need to track the enabled state of a pipe any more, because atomic helpers track this accurately already. Just disable the early returns, since the debug checks might be useful. v2: Don't call drm_helper_disable_unused_functions, it blows up without this check. At least explains why rockchip still needed this old legacy-style state tracing - to work around issues from calling other legacy style functions!
