If the DTS property is specified, the DP bridge should populate a "hdmi-codec" platform device (sound/soc/codecs/hdmi-codec.c).
The "hdmi-codec" device is the communication relayer between the ASoC machine driver and the DP bridge. For example: - Notifies DP bridge when setting hw_param. - Notifies ASoC when jack detection events.
