UDOO: I2S from iMX6q

I recently purchased a UDOO quad (featuring a iMX6 quad chip) and would like to use it as source for digital music. I plan to connect the UDOO via I2S to a ES9023 sabre DAC chip which needs MCLK, LRCK, BCK, DATA input. I have a problem to identify the appropriate output from the iMX6 on the UDOO. In principle iMX6 should support I2S, as its documentation  (http://cache.freescale.com/files/32bit/doc/data_sheet/IMX6DQCEC.pdf?fpsp=1)  says it is capable of outputting I2S via SSI.

 

UDOO provides access to iMX6 available via a number of GPIOs. In their documentation (http://udoo.org/download/files/schematics/UDOO_REV_D_schematics.pdf) page 12 lower right side box the UDOO creators provide the PIN assignment for I2S. However, I cannot make any sense out of this information, and UDOO helpline was not useful.

 

Can anyone provide some advice? I am a weekend DYIer and not very well versed in deep technical matters.

 

Thanks!
