Hi Ryan,

Thanks for taking the time to review this.

The clock source for this is internal and locked in the driver and clock control
handler at 32768Hz.

As much as I want to argue not using platform data :), I can't think of one good
reason not to use it for this (the keyscanner driver has it). I
probably should of
used it from the start.
