No.  It means whatever is standard for the mode (DSP, I2S, left
justified and so on) that the DAI is operating in.  For DSP mode the
above is accurate but the others differ.  The reason why the same
case statement is used for all modes in the DaVinci mode is that when
I2S mode is selected the user provided bit/frame inversion options are
changed before they are used.
