Merge branch 'drm-tda998x-devel' of git://git.armlinux.org.uk/~rmk/linux-arm into...

These updates:
* improve the robustness of the driver wrt races
* improve the compliance for sending infoframes and audio
* re-organise the function order in the driver to group like functions
  together.  (This unfortunately causes a conflict with the change in
  drm-misc, but it should be trivial to solve, although it looks more
  scarey than it really is - sfr has already sent two reports about
  this, one earlier today.)
* simplify tda998x_audio_get_eld and DPMS handling
* power down sections of the chip that we never use
* add some initial preparation for supporting the CEC driver
