What does that "clock" mean?

This chip supports a clock control register which is used to enable the
interface used by the chip to communicate. Here, the interface which you 
can are
SMBUS interface or BC-LINK interface.

I cannot find that in the binding documentation. BTW, did you add that
documentation in the driver patch?

Nope, I missed out on the dt binding documentation for the driver. :(

Will send a seperate patch for the bindings.

Benoit
