OK, thanks I was not able to find a spec that defines this, but I saw a lot of codecs use a single bit clock width. So then equally making the default '1' should also be fine. I still do not like configuring the fsync width in this function. The fsync width needs to be configured for both DSP modes and normal I2S modes and so it seems it would be more appropriate to do this in the hw_params function for this driver.
