21Required properties:
22- compatible : Must be "ti,palmas-gpadc".
23- #io-channel-cells: Should be set to <1>.
24
25Optional sub-nodes:
26ti,channel0-current-microamp: Channel 0 current in uA.
27	Values are rounded to derive 0uA, 5uA, 15uA, 20uA.
28ti,channel3-current-microamp: Channel 3 current in uA.
29	Values are rounded to derive 0uA, 10uA, 400uA, 800uA.
30ti,enable-extended-delay: Enable extended delay.
