+Spreadtrum SC27xx Power Management Integrated Circuit (PMIC)
+
+Required properties:
+- compatible: Should be "sprd,sc2731".
+- reg: SPI chip select.
+- spi-max-frequency: Typically set to 26000000.
+- 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 PMIC 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.
+
+Example:
+pmic: pmic@0 {
+ compatible = "sprd,sc2731";
+ reg = <0>;
+ spi-max-frequency = <26000000>;
+ interrupts = <GIC_SPI 31 IRQ_TYPE_LEVEL_HIGH>;
+ interrupt-controller;
+ #interrupt-cells = <2>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+};
