i.MX53 SSI Interface with Audio DAC WM8523 - Sampling Rate Issue:

[GopiNagaBharath]

Hi All,

We are using Audio DAC WM8523 from Wolfson in our i.mX53 based custom board.

The Audio DAC is interfaced to to the i.MX53 processor through I2S (Audio Mux) & I2C (Software Control Interface).

The WM8523 driver used is from (provided by Wolfson) : http://opensource.wolfsonmicro.com/cgi-bin/gitweb.cgi?p=linux-2.6-asoc.git;a=blob_plain;f=sound/soc/...

When we use this we are getting an error - "No MCLK configured, call set_sysclk() on init" and the System unable to detect the DAC as the sound device.

Has anyone used WM8523 with any of the i.MX series Processors and were able to get it work?

Regards,

Gopi
