Hi,

is there a possibility (parameter in dts file) to get the mclk from the sitara and not from an external oscillator? With external clock it works fine now.

In theory all you need is to route some clock from sitara to aic3100's mclk pin (or so some of the other possible PLL input pins) with suitable pin-control configuration and refer that clock with phandle in the simple-card codec node. In practice I have not done it and at the moment I do not have time to study how it could be done.

Peter, do you know how to do this? Could, for instance, the McASP fclk be routed to codec mclk for pll input?
