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.

Sia Jee Heng (4):
  ASoC: codec: hdmi-codec: Support IEC958 encoded PCM format
  drm: bridge: adv7511: Support I2S IEC958 encoded PCM format
  dt-bindings: sound: Intel, Keembay-i2s: Add hdmi-i2s compatible string
  ASoC: Intel: KMB: Support IEC958 encoded PCM format

[>>] Hi Mark, if there is no issue to the flows and no concern from the rest, I think the changes to the Sound can be merged first. I shall submit the DRM patch to the DRM community later.
