Pull drm updates from Dave Airlie:
 "This is the main drm pull request for 4.14 merge window.

  I'm sending this early, as my continuing journey into fatherhood is
  occurring really soon now, I'm going to be mostly useless for the next
  couple of weeks, though I may be able to read email, I doubt I'll be
  doing much patch applications or git sending. If anything urgent pops
  up I've asked Daniel/Jani/Alex/Sean to try and direct stuff towards
  you.

  Outside drm changes:

  Some rcar-du updates that touch the V4L tree, all acks should be in
  place. It adds one export to the radix tree code for new i915 use

drm/bridge/sii8620: Fix memory corruption

2017-08-24T17:06:32+00:00

Function sii8620_mt_read_devcap_reg_recv() used to read array index
from a wrong msg register, which caused writing out of array
bounds. It led to writing on other fields of struct sii8620.

snd_pcm_ops are not supposed to change at runtime. All functions

drm: Nuke drm_atomic_helper_connector_dpms

2017-08-08T12:48:48+00:00

It's dead code, the core handles all this directly now.

The only special case is nouveau and tda988x which used one function
for both legacy modeset code and -nv50 atomic world instead of 2
vtables. But amounts to exactly the same.

v2: Rebase over the panel/brideg refactorings in stm/ltdc.

drm: bridge: synopsys/dw-hdmi: Provide default configuration function for HDMI 2.0 PHY

2017-08-08T08:39:56+00:00

Currently HDMI 2.0 PHYs do not have a default configuration function.

As *some* of the HDMI 2.0 PHYs have the same register layout as the 3D
PHYs we can provide the same default configuration function for both
and still let user overwrite this with custom configuration function
if needed.

If, for some reason, the PHY is custom or has a register different
register layout then custom configuration function *must* be provided
in order for the system to work correctly. As we prefer the pdata
provided configuration function over the internal one this change
will not make any impact in custom platforms.
