Thanks. I got the code, included all the ASoc stuff in my local tree
and rebuilt the kernel. If i understand the docs correctly I have
to write a codec driver for my audio chip and some machine code to set
up the particulars for my board (clocks, io pins etc.).
Am I missing something?
The codec we use has no control functions (no i2c/spi comm) it simply
plays back the samples it reads on the i2s bus. This should thus
translate to a simple codec driver. Is there a codec driver that uses
i2s on the at91 that I can use as a base for my driver?
I haven't really understood yet how to include the machine code.
Should this be done in the same way as the other platform drivers in
arch/arm/mach-at91rm9200/board-xxx.c? Is there some sample code that I
can use as a model?
Thanks again for the assistance.
