+Texas Instruments Palmas family
+
+The Palmas familly are Integrated Power Management Chips.
+These chips are connected to an i2c bus.
+
+
+Required properties:
+- compatible : Must be "ti,palmas";
+ For Integrated power-management in the palmas series, twl6035, twl6037,
+ tps65913
+- interrupts : This i2c device has an IRQ line connected to the main SoC
+- interrupt-controller : Since the palmas support several interrupts internally,
+ it is considered as an interrupt controller cascaded to the SoC one.
+- #interrupt-cells = <1>;
+- interrupt-parent : The parent interrupt controller.
+
+Optional node:
+- Child nodes contain in the palmas. The palmas family is made of several
+ variants that support a different number of features.
+ The child nodes will thus depend of the capability of the variant.
+- mux-pad1 if a value is given it will be used for the pad1 mux
+- mux-pad2 if a value us given it will be used for the pad2 mux
+- power-ctrl if a value is given it will be written to the POWER_CTRL register
+
+Example:
+/*
+ * Integrated Power Management Chip Palmas
+ */
+palmas@48 {
+ compatible = "ti,palmas";
+ reg = <0x48>;
+ interrupts = <39>; /* IRQ_SYS_1N cascaded to gic */
+ interrupt-controller;
+ #interrupt-cells = <1>;
+ interrupt-parent = <&gic>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ ti,mux-pad1 = <0x00>;
+ ti,mux-pad2 = <0x00>;
+ ti,power-ctrl = <0x03>;
+
+ palmas_pmic {
+ compatible = "ti,palmas_pmic";
+ regulators {
+ smps12_reg: smps12 {
+ regulator-min-microvolt = < 600000>;
+ regulator-max-microvolt = <1500000>;
+ regulator-always-on;
+ regulator-boot-on;
+ ti,warm-sleep = <0>;
+ ti,roof-floor = <0>;
+ ti,mode-sleep = <0>;
+ ti,warm-reset = <0>;
+ ti,tstep = <0>;
+ ti,vsel = <0>;
+ };
+ };
+ ti,ldo6-vibrator = <0>;
