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

These changes from Liviu add support for atomic mode setting, add the
TMDS clock limitation according to the device, and ensure that we
correctly clean up in the unbind function.

* 'drm-tda998x-devel' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
  drm/i2c: tda998x: Add support for atomic modesetting
  drm/i2c: tda998x: increase the supported dotclock frequency to 165MHz for TDA19988
  drm/i2c: tda998x: unregister the connector in the unbind function
