The simple-card driver currently accepts a clock node in the cpu dai
sub-node and only uses it as an alternative to the
'system-clock-frequency' property to get the current frequency.
This patch adds another use of the passed clock node. If mclk-fs is
specified, the clock will be set to the calculated rate (stream rate *
mclk_fs) in hw_params. This allows platforms to pass a tuneable clock
as phandle that will automatically be set to the right rates.

Having codec is nice balance ?
Ah, yes, why not. Will post a v2.
Thanks,
