Merge tag 'topic/drm-misc-2016-06-15' of 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. Jon cc'ed as fyi.

...
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.
Use the upper_32_bits() macro instead of the four line equivalent that
triggers a GCC warning on 32 bits x86:
drivers/gpu/drm/vmwgfx/vmwgfx_cmdbuf.c: In function 'vmw_cmdbuf_header_submit':
drivers/gpu/drm/vmwgfx/vmwgfx_cmdbuf.c:297:25: warning: right shift count >= width of type [-Wshift-count-overflow]
val = (header->handle >> 32); ^
And use the lower_32_bits() macro instead of and-ing with a 32 bits
mask.

Now that the core helpers support nonblocking atomic commits there's
no need to invent that wheel separately (instead of fixing the bug in
the atomic implementation of virtio, as it should have been done!).
