The only significant difference I see in the machine drivers is that the 
clock dividers are smaller in this bdw-rt5660 case, the bitclock is 4.8 
MHz v. 2.4 MHz in the other bdw-rt5677. It's not very clear to me why 
there is a need to have different clock and SSP settings, but since the 
patch that was suggested to be reverted touches the clock generation 
maybe there's a connection?
