regulator: 88pm800: add regulator driver for 88pm800
Add the regulator driver for PMIC 88pm800 including device tree
support.
88pm800 is an I2C-based power-management IC containing voltage
regulators, a real-time clock, and some general purpose ADC devices,

+Marvell 88PM800 regulator
+
+Required properties:
+- compatible: "marvell,88pm800"
+- reg: I2C slave address
+- regulators: A node that houses a sub-node for each regulator within the
+ device. Each sub-node is identified using the node's name (or the deprecated
+ regulator-compatible property if present), with valid values listed below.
+ The content of each sub-node is defined by the standard binding for
+ regulators; see regulator.txt.
+
+The valid names for regulators are:
+
+ buck1, buck2, buck3, buck4, buck5, ldo1, ldo2, ldo3, ldo4, ldo5, ldo6, ldo7,
+ ldo8, ldo9, ldo10, ldo11, ldo12, ldo13, ldo14, ldo15, ldo16, ldo17, ldo18, ldo19
+
+Example:
+
+ pmic: 88pm800@31 {
+ compatible = "marvell,88pm800";
+ reg = <0x31>;
+
+ regulators {
+ buck1 {
+ regulator-min-microvolt = <600000>;
+ regulator-max-microvolt = <3950000>;
+ regulator-boot-on;
+ regulator-always-on;
+ };
+ ldo1 {
+ regulator-min-microvolt = <600000>;
+ regulator-max-microvolt = <15000000>;
+ regulator-boot-on;
+ regulator-always-on;
+ };
+...
+ };
+ };
