The wega board has a TLV320AIC3007 connected via McASP0. In the default configuration, no external crystal is mounted. We run a system clock of 25 MHz, so we use the audio codec PLL for audio clock generation.
It is great that the "ti,da830-evm-audio" works for you. I hope I will have time soon to work on the McASP driver's CCF support in the near future.
