+Motorola CPCAP PMIC ADC binding
+
+Required properties:
+- compatible: Should be "motorola,cpcap-adc" or "motorola,mapphone-cpcap-adc"
+- interrupts: The interrupt number for the ADC device
+- interrupt-names: Should be "adcdone"
+- #io-channel-cells: Number of cells in an IIO specifier
+
+Example:
+
+cpcap_adc: adc {
+	compatible = "motorola,mapphone-cpcap-adc";
+	interrupt-parent = <&cpcap>;
+	interrupts = <8 IRQ_TYPE_NONE>;
+	interrupt-names = "adcdone";
+	#io-channel-cells = <1>;
+};
