should be 48kHz or 96kHz? If the final goal is to explicitly represent
all links in the system (ABE, Phoenix, McBSP, etc), then ABE link
should expose somehow that it delives upsampled data. If that assumption
is true, then TWL6030 DAI should support 96kHz.
A second concern is that runtime constraints will prevent rates
supported by the system, when the constraints are only valid for the
link. For example, if the TWL6030 CODEC adds a contraint for 96kHz,
then it prevents the whole system to play 48kHz, which is supported
when ABE is enabled since ABE upsamples it.
