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

This series:
* adds support for interlaced video modes to the ipu-v3 driver
  and dw_hdmi bridge.
* reworks the dw_hdmi connector enable/disable support, to ensure that
  when DRM disables the output, it stays disabled irrespective of the
  hotplug state.
* adds support for connector forcing, so we can force the hotplug state
  for this connector.
* adds the ALSA AHB audio driver to the bridge: Iwai has acked the
  audio driver.
* a few fixes to the ACR calculations to allow more modes to work with
  audio on iMX6.

Fabio has independently tested this series, so all patches here carry
his tested-by tag.
