Why do these two differ? It's very unusual to see different formats and generally indicates a bug in one of the drivers involved that's being worked around. The omission of I2S is understandable since the CPU only does I2S (though ideally it'd be specified) but the inversion of the bit and frame clocks for the CPU only looks like the CPU is generating inverted clocks by default.
