I2S Audio and MCLK on ADV7610

We have an ADV7610 design where we feed the I2S audio to an application processor.  We have hooked up the LRCLK, the SCLK and IS20 outputs from the ADV7610.  We require only stereo audio, not multi-channel; we don't plan to connect the I2S1, I2S2 or I2S3 audio outputs

 

It is not clear to us what to do with the MCLK from the ADV7610.  The ADV7610 is an I2S Master, right?  The MCLK pin seems to be an output only.

In what situation would we use the MCLK on this part?
