The trick is figuring out if it's best to vary the input clock or to use the FLL to adapt a fixed input clock,
For simple-audio-card you can set the "clock" property if you want that clock to be changed/enabled/disabled. But that doesn't seem to be the way to go, at least it was NAKed by Rob for the audio-graph-card. I don't see a way to figure out if MCLK should be controlled by simple-*-card without adding further properties to the device tree.
If the card has a clock API clock as sysclk then set_sysclk(() should be configuring that clock.
