The driver has been extended to optionally get its operational
mode, regulator init data and LED naming from the devicetree.

 - reg:                 Specifies the I2C slave address
 
-Example:
+Optional sub-node:
+
+This subnode selects the chip's operational mode.
+There can be at most one single available subnode.
+
+- regulator: presence of this sub-node puts the chip in regulator mode.
+       see ../regulator/regulator.yaml
+
+- led: presence of this sub-node puts the chip in led mode.
+       Optional properties:
+       - function : see ../leds/common.txt
+       - color    : see ../leds/common.txt
+       - label    : see ../leds/common.txt
