[SGTL5000] SGTL5000 in I2S slave mode

For some reason, we need to use SGTL5000 DAC in I2S mode.

In my environment, fs=48khz, mclk=256fs=12.288Mhz, sck=64fs=3.072Mhz. VDDIO=VDDA=3.3V, VDDD=1.2V.

We set SGTL5000 in slave mode and SYS_FS=48k, MCLK_FREQ=256fs.

But no audio output.

(Same power supply was ok by using SGTL5000 in master mode by iMX6 driver,

but we change mclk to 12.288 , and using slave mode, no audio come out)

Anyone have the successful to use SGTL5000 in slave mode,

and can give us the setting sequence of I2C command ?

Or can some one can tell me how to debug by some I2C command ?

My SGTL5000 version is 0X11.
