Im writing a driver to control the sai in kernel space (not alsa) 

Im just wondering, if the transmitter is enabled but theres no data in the fifo will clk and fsync still be output? Because im calling the trigger function of the fsl_sai driver but I see no clk or fsync being generated on the pins with my scope.

Nevermind i think it was runtime power management that was messing me up.
