mx27 ssi interface program

[zhangjay]

Dear all

I am using imx27 cpu as your board processor, I want to use the ssi interface as i2s to control TW2835 chip which has audio codec inside, but I cannot find any sample codes to refer.

Is there any example I can refer to?

I can find the functions in ssi.c, but I don't know how to use them.

I want to use the ssi interface as i2s.

You need a codec driver for the TW2835. Could not find it under soc/codecs, so you would need to add support for this codec first.
