+Motorola CPCAP PMIC device tree binding
+
+Required properties:
+- compatible		: One or both of "motorola,cpcap" or "ste,6556002"
+- reg			: SPI chip select
+- interrupts		: The interrupt line the device is connected to
+- interrupt-controller	: Marks the device node as an interrupt controller
+- #interrupt-cells	: The number of cells to describe an IRQ, should be 2
+- #address-cells	: Child device offset number of cells, should be 1
+- #size-cells		: Child device size number of cells, should be 0
+- spi-max-frequency	: Typically set to 3000000
+- spi-cs-high		: SPI chip select direction
+
+Optional subnodes:
+
+The sub-functions of CPCAP get their own node with their own compatible values,
+which are described in the following files:
+
+- ../power/supply/cpcap-battery.txt
+- ../power/supply/cpcap-charger.txt
+- ../regulator/cpcap-regulator.txt
+- ../phy/phy-cpcap-usb.txt
+- ../input/cpcap-pwrbutton.txt
+- ../rtc/cpcap-rtc.txt
+- ../leds/leds-cpcap.txt
+- ../iio/adc/cpcap-adc.txt
+
+The only exception is the audio codec. Instead of a compatible value its
+node must be named "audio-codec".
+
+Required properties for the audio-codec subnode:
+
+- #sound-dai-cells = <1>;
+
+The audio-codec provides two DAIs. The first one is connected to the
+Stereo HiFi DAC and the second one is connected to the Voice DAC.
+
+Example:
+
+&mcspi1 {
+	cpcap: pmic@0 {
+		compatible = "motorola,cpcap", "ste,6556002";
+		reg = <0>;	/* cs0 */
+		interrupt-parent = <&gpio1>;
+		interrupts = <7 IRQ_TYPE_EDGE_RISING>;
+		interrupt-controller;
+		#interrupt-cells = <2>;
+		#address-cells = <1>;
+		#size-cells = <0>;
+		spi-max-frequency = <3000000>;
+		spi-cs-high;
+
+		audio-codec {
+			#sound-dai-cells = <1>;
+
+			/* HiFi */
+			port@0 {
+				endpoint {
+					remote-endpoint = <&cpu_dai1>;
+				};
+			};
+
+			/* Voice */
+			port@1 {
+				endpoint {
+					remote-endpoint = <&cpu_dai2>;
+				};
+			};
+		};
+	};
+};
