This is an I2S bus driver for the MPC5200 PSC device. It is probably will not be merged as-is because it uses v1 of the ASoC API, but I want to get it out there for comments.
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?
