clock node (= common clock), or "system-clock-frequency"
(if system doens't support common clock)
Note:
* For 'format', 'frame-master', 'bitclock-master', 'bitclock-inversion' and
'frame-inversion', the simple card will use the settings of CODEC for both
CPU and CODEC sides as we need to keep the settings identical for both ends
of the link.
Example:
