Hi,

Note that this node needs the audio PLL clock which is not submitted yet. So,
this series can't be applied right now: we have to wait for the audio PLL
driver and binding to be accepted and included first.

I send it right now so that it's not forgotten and easyer to track. Moreover,
the binding won't certainly change.

Bye,
