+Required node properties:

+Optional properties:
+
+Numeric registors initialiaztion:
+
+- nct7802,reg-init : one of more sets of 4 cells.  The first cell
+  is the page address, the second a register address within the page,
+  the third cell contains a mask to be ANDed with the existing register
+  value, and the fourth cell is ORed with the result to yield the
+  new register value. If the third cell has a value of zero,
+  no read of the existing value is performed.
+
+Example nct7802 node:
+
+nct7802 {
+	compatible = "nuvoton,nct7802";
+	reg = <0x2a>;
+	nct7802,reg-init =

+		<0 0x22 0x03 0x02>; // RTD1_MD = 2
