Unfortunately the omap-mcbsp driver only supports synchronous configuration for tx/rx (since almost all McBSP instance can only be used this way). The first stream will configure both tx and rx to have the same properties. Even if you are using McBSP1 which has separate FSX and FSR lines, the driver does not have support for this. From HW point of view this configuration is valid (not something I would expect in any product). I don't think there are or will be other designs than your using this mode... But, if you add some comment around the masking of CLKXM and CLKRM bits that would be great.
Do you mean adding it to the commit message or to the code? or both?
Since this is something that the driver has not meant to support officially, I prefer both. I just hope that HW designers will not get ideas based on this ;)
