The TWL4030 datasheet does not appear to be a model of clarity in this area but it looks awfully like mode A with an inverted bit clock (the data appears to be being driven rather than sampled on the rising edge but the first bit does start on the falling edge of the frame clock). This means the Beagle code looks about right unless I'm misreading something.
What I've seen few codec specs there is no uniform way for different DSP formats between their specifications except Wolfson codecs. So I use to keep those as a reference and match codec accordingly. Like in AIC3x where bit-clock polarity is fixed.
