Merge series "Add HDMI support for Intel KeemBay I2S" from Sia Jee Heng <jee.heng.sia@intel.com>:
The below patch series are to support Audio over HDMI.
The modification in this patch series shall allow I2S driver
to playback standard PCM format and IEC958 encoded format to
the ADV7511 HDMI chip.
ALSA IEC958 plugin will be used to compose the IEC958 format.
Existing hdmi-codec driver only support standard pcm format.
Support of IEC958 encoded format passdown from ALSA IEC958 plugin
is needed so that the IEC958 encoded data can be streamed to the
HDMI chip.
