+Motorola CPCAP PMIC battery charger binding
+
+Required properties:
+- compatible: Shall be "motorola,cpcap-charger" or
+	      "motorola,mapphone-cpcap-charger"
+- interrupts: Interrupts used on the CPCAP PMIC
+- interrupt-names: Names of the interrupts
+- io-channels: IIO ADC channels used by the charger
+- io-channel-names: Names of the IIO ADC channels
+
+Optional properties:
+- mode-gpios: Optionally CPCAP charger can have a companion wireless
+	      charge controller that is controlled with two GPIOs
+
+Example:
+
+cpcap_charger: charger {
