7b47c66cfa Merge arlied/drm-next into drm-misc-next
We need to pull 66660d4cf2 (drm: add connector info/property for
non-desktop displays [v2]) into drm-misc-next to continue the development
of the display rotation series.

Effectively this also pulls 4.15-r2 into drm-misc-next.

ca0e68e21a drm/prime: skip CPU sync in map/unmap dma_buf
Dma-bufs should already be device coherent, as they are only pulled in the
CPU domain via the begin/end cpu_access calls. As we cache the mapping set
up by dma_map_sg a CPU sync at this point will not actually guarantee proper
coherency on non-coherent architectures, so we can as well stop pretending.

This is an important performance fix for architectures which need explicit
cache synchronization and userspace doing lots of dma-buf imports.
Improves Weston on Etnaviv performance 5x, where before this patch > 90%
of Weston CPU time was spent synchronizing caches for buffers which are
already device coherent.

ff71c2cf5e drm/sun4i: use sun4i_tcon_of_table to check if a device node is a TCON
The sun4i DRM driver maintains a list of compatible strings it uses to
check if a device node within the display component graph is a TCON.
The TCON driver also has this list, used to bind the TCON driver to
the device. These two lists are identical.

Instead of maintaining two identical lists, export the list from the
TCON driver for the DRM driver to use.

a152992062 drm/imx: always call wait_for_flip_done in commit_tail
drm_atomic_helper_wait_for_vblanks will go away in the future.

The new drm_atomic_helper_setup_commit in 4.15 expects that blocking commits
have completed flipping before the commit_tail returns. This must be ensured
by calling wait_for_vblanks or wait_for_flip_done, where flip_done might do
a less agressive wait, which is fine for imx-drm.

Commit d178e034d5 ("drm: omapdrm: Move FEAT_DPI_USES_VDDS_DSI feature

to configure DPI VDDS. The SoC match entries were incorrect, they should
have matched on the machine name instead of the SoC family. Fix it.

The result was observed on OpenPandora with OMAP3530 where the panel only
had the Blue channel and Red&Green were missing. It was not observed on
GTA04 with DM3730.

23970e150a omapdrm: hdmi4: Correct the SoC revision matching
I believe the intention of the commit 2c9fc9bf45
("drm: omapdrm: Move FEAT_HDMI_* features to hdmi4 driver")
was to identify omap4430 ES1.x, omap4430 ES2.x and other OMAP4 revisions,
like omap4460.

By using family=OMAP4 in the match the code will treat omap4460 ES1.x in a
same way as it would treat omap4430 ES1.x

This breaks HDMI audio on OMAP4460 devices (PandaES for example).

Correct the match rule so we are not going to get false positive match.

1b6fba458c drm/bridge: adv7511/33: Fix adv7511_cec_init() failure handling
If the device tree for a board did not specify a cec clock, then
adv7511_cec_init would return an error, which would cause adv7511_probe()
to fail and thus there is no HDMI output.

There is no need to have adv7511_probe() fail if the CEC initialization
fails, so just change adv7511_cec_init() to a void function. In addition,
adv7511_cec_init() should just return silently if the cec clock isn't
found and show a message for any other errors.

An otherwise correct cleanup patch from Dan Carpenter turned this broken
failure handling into a kernel Oops, so bisection points to commit
7af35b0add ("drm/kirin: Checking for IS_ERR() instead of NULL") rather
than 3b1b975003 ("drm: adv7511/33: add HDMI CEC support").

a76dfe350c drm/atomic: make drm_atomic_helper_wait_for_vblanks more agressive
drm_atomic_helper_setup_commit expects that flipping of previous commits
has happened when it is called to set up a new commit. This can be violated
by commits where userspace doesn't get a flip completion event to
synchronize against i.e. legacy modesets and property changes.

The expectation is that those are done by blocking commits, which wait for
completion. Most drivers call drm_atomic_helper_wait_for_vblanks in the
commit_tail to ensure completion, but the wait for next vblank might not
actually happen if the commit didn't change any planes.

Make the wait more agressive by also waiting if no planes changed. This
is the minimal regression fix for the 4.15 kernel series. Long term
drivers should switch away from drm_atomic_helper_wait_for_vblanks and
use drm_atomic_helper_wait_for_flip_done instead.
