+- dok-gpios: Valid DC power has been detected (active low, input), optional if uok-gpios is provided
+- uok-gpios: Valid USB power has been detected (active low, input), optional if dok-gpios is provided
+
+Optional properties:
+- cen-gpios: Charge enable pin (active low, output)
+- chg-gpios: Charger status pin (active low, input)
