If you can get by without the I2S master clock, you can map the I2S
signals to the SPI pins, which are brought out. I'm not sure if you need
the master clock if you want to be an I2S master - there are frame and
bit clocks too, maybe that's enough. I only used it in slave mode, so I
don't know. Check the EP9301 manual, there's a chapter on the I2S
controller.
