struct audio_stream_cmd_get_clock_domain_req

AUDIO_STREAM_CMD_GET_CLOCK_DOMAIN

Fetch the hardware clock domain for this device.

On products containing audio devices that are not locked to the local system clock, the board

driver will provide a clock tree entry to the audio driver at driver startup time. From that,

the audio driver can extract the clock domain and provide it to the sender, upon receiving this

command. This domain value is all that the sender needs, in order to locate controls for that

clock domain in the clock tree and trim that clock domain's rate.

On products containing audio devices that are locked to the local system monotonic clock, a clock

domain value of 0 should be returned.

Must not be used with the NO_ACK flag.
