From: Jonathan Cameron <Jonathan.Cameron@xxxxxxxxxx>
Simple conversion of the binding doc for this subnode of the palmas
PMIC.
Given age of driver and lack interaction with original authors,
I've guessed at Tony for a maintainer on this one. Tony, if you
are happy with that great, otherwise I can default back to myself.

-Optional sub-nodes:
-ti,channel0-current-microamp: Channel 0 current in uA.
- Values are rounded to derive 0uA, 5uA, 15uA, 20uA.
-ti,channel3-current-microamp: Channel 3 current in uA.
- Values are rounded to derive 0uA, 10uA, 400uA, 800uA.
-ti,enable-extended-delay: Enable extended delay.
