Merge branch 'tda998x-fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-cubox into drm-next

These are a number of fixes from the patch set which Jean-Francois has
been working on which I think are important to be merged during -rc, and
have been tested independently here.  I've been in discussion with Rob,
who is happy that I send these directly to you.

* 'tda998x-fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-cubox:
  drm/i2c: tda998x: fix the ENABLE_SPACE register
  drm/i2c: tda998x: set the PLL division factor in range 0..3
  drm/i2c: tda998x: force the page register at startup time
  drm/i2c: tda998x: free the CEC device on encoder_destroy
  drm/i2c: tda998x: check the CEC device creation
  drm/i2c: tda998x: fix bad value in the AIF
