+* tps65917 regulator IP block devicetree bindings
+
+Required properties:
+- compatible : Should be
+ ti,tps65917-pmic
+
+- interrupt-parent : The parent interrupt controller which is tps65917.
+- interrupts : The interrupt number and the type which can be looked up here:
+ arch/arm/boot/dts/include/dt-bindings/interrupt-controller/irq.h
+- interrupts-name: The names of the individual interrupts.
+
+Optional nodes:
+- regulators : Must contain a sub-node per regulator from the list below.
+ Each sub-node should contain the constraints and initialization
+ information for that regulator. See regulator.txt for a
+ description of standard properties for these sub-nodes.
+ Additional custom properties are listed below.
+
+ Optional sub-node properties:
+ ti,warm-reset - maintain voltage during warm reset(boolean)
+ ti,roof-floor - This takes as optional argument on platform supporting
+ the rail from desired external control. If there is no argument then
+ it will be assume that it is controlled by NSLEEP pin.
+ The valid value for external pins are:
+ ENABLE1 then 1,
+ ENABLE2 then 2 or
+ NSLEEP then 3.
+ ti,mode-sleep - mode to adopt in pmic sleep 0 - off, 1 - auto,
+ 2 - eco, 3 - forced pwm
+ ti,smps-range - OTP has the wrong range set for the hardware so override
+ 0 - low range, 1 - high range.
+
+- ti,system-power-controller: Telling whether or not this pmic is controlling
+ the system power.
+
+Example:
+
+#include <dt-bindings/interrupt-controller/irq.h>
+
+pmic {
+ compatible = "ti,tps65917-pmic";
+ interrupt-parent = <&tps65917>;
+ interrupts = <14 IRQ_TYPE_NONE>;
+ interrupts-name = "short-irq";
+
+ ti,system-power-controller;
+
+ regulators {
+ smps1_reg : smps1 {
+ regulator-name = "smps1";
+ regulator-min-microvolt = < 600000>;
+ regulator-max-microvolt = <1500000>;
+ regulator-always-on;
+ regulator-boot-on;
+ ti,warm-reset;
+ ti,roof-floor = <1>; /* ENABLE1 control */
+ ti,mode-sleep = <0>;
+ ti,smps-range = <1>;
+ };
+
+ ldo1_reg: ldo1 {
+ regulator-name = "ldo1";
+ regulator-min-microvolt = <2800000>;
+ regulator-max-microvolt = <2800000>;
+ };
+ };
+};
