Wait, there is no option for selecting I2SCLK in the manual. That is
behind the MUX along with Mpll/Epll Out etc.
In the driver we actually have all the correct options : PCLK or
CLKAUDIO(which is the output of the MUX).

The IMS bit can select only either PCLK or CLKAUDIO.So, i guess
 the patch is fine as it is.
