Did imx_ssi_probe go successfully? What is the error log you are getting?
The controller probes but there's no perceptible activity on the pins
when we try to reset the CODEC so no register I/O.
Take a look at pcm043_ac97_cold_reset/pcm043_ac97_warm_reset at
arch/arm/mach-imx/mach-pcm043.c
to see how GPIO pins are handled for resetting ac97 codec on this platform.
