S32_LE Format not supported by imx6qdl SSI Controller

[shammi112]

Hello,

I am trying to integrate MIC(ics43432) with imx6qdl based board. SSI is working in master mode and generating the

clock as required.  Mic output data as steam of 24 bits(32 SCK cycle frame). 1st bit and 26-32  is high impedance out of 32 bits.  Bit 1 to 25 contains data. But if i am passing S32_LE to arecord, i am getting format not supported error. 

Regards,

SHAMMI
