+* Dialog DA9063 Power Management Integrated Circuit (PMIC)
+
+Required properties:
+- compatible : Should be "dialog,da9063"
+- interrupt-parent : phandle pointing to the interrupt controller
+- interrupts : interrupt number and flags in interrupt-parent
+ for the chip IRQ line. Interrupt bindings are documented here:
+ Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
+
+Sub-nodes:
+- regulators : Contain the regulator nodes. The DA9063 regulators are
+ bound using their names as listed below:
+
+ bcore1 : regulator BCORE1
+ bcore2 : regulator BCORE2
+ bpro : regulator BPRO
+ bmem : regulator BMEM
+ bio : regulator BIO
+ bperi : regulator BPERI
+ ldo1 : regulator LDO1
+ ldo2 : regulator LDO4
+ ldo3 : regulator LDO3
+ ldo4 : regulator LDO4
+ ldo5 : regulator LDO5
+ ldo6 : regulator LDO6
+ ldo7 : regulator LDO7
+ ldo8 : regulator LDO8
+ ldo9 : regulator LDO9
+ ldo10 : regulator LDO10
+ ldo11 : regulator LDO11
+
+ The PMIC can also be configured to merge both bcore1/2 into a single
+ supply and to merge bmem and bio into a single supply. In this case,
+ the following regulators are bound instead of bcore1/2 and bpro/bmem:
+
+ bcores-merged : merged regulators BCORE1, BCORE2
+ bmem-bio-merged : merged regulators BMEM, BIO
+
+ See Documentation/devicetree/bindings/regulator/regulator.txt for
+ binding details of individual regulator device nodes.
+
+
+Examples:
+
+&i2c1 {
+ status = "okay";
+
+ pmic@58 {
+ compatible = "dialog,da9063";
+ reg = <0x58>;
+ interrupt-parent = <&gpio4>;
+ interrupts = <17 0x8>; /* active-low GPIO4_17 */
+
+ regulators {
+ bcore1 {
+ regulator-min-microvolt = <300000>;
+ regulator-max-microvolt = <1570000>;
+ };
+
+ bcore2 {
+ regulator-min-microvolt = <300000>;
+ regulator-max-microvolt = <1570000>;
+ };
+
+ /* ... */
+ };
+ };
+};
