drm/imx: fix commit_tail for new drm_atomic_helper_setup_commit

Since commit 080de2e5be ("drm/atomic: Check for busy planes/connectors before
setting the commit"), drm_atomic_helper_setup_commit expects that blocking
commits have completed flipping before the commit_tail returns. Add the missing
wait_for_flip_done to commit_tail to ensure this.

adbe5c5cd3 drm/i915: Enable IPS with only sprite plane visible too, v4.
This comment predates atomic, and I think with the way we currently
track IPS, it's safe to enable this for the case we switch too.

Changes since v1:
- Keep IPS enabled when switching planes.
Changes since v2:
- Enable IPS when at least one plane is enabled. (Ville)
Changes since v3:
- Actually do what was advertised in v3, sigh! (Ville, CI)

ips_enabled was used as a variable of whether IPS can be enabled or not,
but should be used to test whether IPS is actually enabled.

Changes since v1:
- Call needs_modeset on new crtc state. (Ville)
- IPS can be enabled with sprite plane enabled too. (Ville)
- Fix CDCLK vs IPS workaround. (Ville)
Changes since v2:
- Only re-enable fastset when inheriting mode. (Ville)
- Put the conditions for enabling and disabling IPS in a helper.
Changes since v3:
- Keep the max_cdclk workaround working. (Ville)
- Also check logical cdclk out of paranoia.
- Remove planes check from IPS disable function for initial disable.
- Remove assert_plane_enabled/disabled checks and use
  crtc_state->active_planes for hsw_enable_ips only, always allow
  calling hsw_disable_ips to disable it initially in hw.

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.

5643205c63 drm/i915: Avoid PPS HW/SW state mismatch due to rounding
We store a SW state of the t11_t12 timing in 100usec units but have to
program it in 100msec as required by HW. The rounding used during
programming means there will be a mismatch between the SW and HW states
of this value triggering a "PPS state mismatch" error. Avoid this by
storing the already rounded-up value in the SW state.

Note that we still calculate panel_power_cycle_delay with the finer
100usec granularity to avoid any needless waits using that version of
the delay.

bf25dac38f drm: omapdrm: Fix DPI on platforms using the DSI VDDS
Commit d178e034d5 ("drm: omapdrm: Move FEAT_DPI_USES_VDDS_DSI feature
to dpi code") replaced usage of platform data version with SoC matching
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.

dbb58bfd9a drm/bridge: Fix lvds-encoder since the panel_bridge rework.
The panel_bridge bridge attaches to the panel's OF node, not the
lvds-encoder's node.  Put in a little no-op bridge of our own so that
our consumers can still find a bridge where they expect.

This also fixes an unintended unregistration and leak of the

ebe32c3e28 drm/bridge: synopsys/dw-hdmi: Enable cec clock
Support the "cec" optional clock. The documentation already mentions "cec"
optional clock and it is used by several boards, but currently the driver
doesn't enable it, thus preventing cec from working on those boards.

And even worse: a /dev/cecX device will appear for those boards, but it
won't be functioning without configuring this clock.

Changes:
v4:
- Change commit message to stress the importance of this patch

v3:
- Drop useless braces

v2:
- Separate ENOENT errors from others
- Propagate other errors (especially -EPROBE_DEFER)

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").

Based on earlier patches from Arnd and John.

7fdf165a52 drm/radeon: remove init of CIK VMIDs 8-16 for amdkfd
VMIDs 8-16 in Kaveri were reserved for use by the amdkfd driver.
Because we removed amdkfd support from radeon, those VMIDs are now
used by radeon and are initialized by radeon.

This patch removes the function that initialized those VMIDs for amdkfd
use.
This initialization overridden the radeon initialization and caused GPU
faults and GUI crashed.

Some drivers like i915 start with crtc's enabled, but with deferred
fbcon setup they were no longer disabled as part of fbdev setup.
Headless units could no longer enter pc3 state because the crtc was
still enabled.

Fix this by calling restore_fbdev_mode when we would have called

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.
