Hi,
The bit clock polarity has been configured incorrectly in the McASP driver for a
long time. IB_NF, NB_IF and IB_IF was not correct on the receive side since they
were selecting the same edge as we used for the tx.
The driver only had support for DSP_B mode (and probably AC97, but I can not
test that). All other formats were broken (DSP_A, I2S, LEFT_J, etc).
With this series the following formats will be supported by the McASP driver:
- DSP_B
- AC97
- DSP_A (new)
- I2S (new)
- LEFT_J (new)
Non supported modes will return error from now on.
Regards,
Peter
