The driver is assuming a capture stream exists. My codec is output only.

I'm using external clocking, but the driver should support using the
mpc5200 for clocking. That's a little complicated since you have to
compute the divisors. For example the Phytec pcm030 board has a
33.3333Mhz xtal and runs at 400Mhz.

In order to reduce options, can the psc-i2s driver always try to use
mpc5200 clocking, then let the codec or fabric driver override it?
