From: S Twiss <stwiss.opensource@diasemi.com>

Add device tree bindings for the DA9062 driver

Signed-off-by: Steve Twiss <stwiss.opensource@diasemi.com>

Changes in V2:
- Dropped the RTC and Onkey binding information in this patch-set
Those drivers have been dropped from this patch set and the
binding information has been removed accordingly.

This patch applies against linux-next and v4.1-rc3

+* Dialog DA9062 Power Management Integrated Circuit (PMIC)
+
+DA9062 consists of a large and varied group of sub-devices:
+
+Device Supply Names Description
+------ ------------ -----------
+da9062-regulator : : LDOs & BUCKs
+da9062-watchdog : : Watchdog Timer
+
+======
+
+Required properties:
+
+- compatible : Should be "dlg,da9062".
+- reg : Specifies the I2C slave address (this defaults to 0x58 but it can be
+ modified to match the chip's OTP settings).
+- interrupt-parent : Specifies the reference to the interrupt controller for
+ the DA9062.
+- interrupts : IRQ line information.
+- interrupt-controller
+
+See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt for
+further information on IRQ bindings.
+
+Sub-nodes:
+
+- regulators : This node defines the settings for the LDOs and BUCKs. The
+ DA9062 regulators are bound using their names listed below:
+
+ buck1 : BUCK_1
+ buck2 : BUCK_2
+ buck3 : BUCK_3
+ buck4 : BUCK_4
+ ldo1 : LDO_1
+ ldo2 : LDO_2
+ ldo3 : LDO_3
+ ldo4 : LDO_4
+
+ The component follows the standard regulator framework and the bindings
+ details of individual regulator device can be found in:
+ Documentation/devicetree/bindings/regulator/regulator.txt
+
+
+- watchdog: This node defines the settings for the watchdog driver associated
+ with the DA9062 PMIC. The compatible = "dlg,da9062-watchdog" should be added
+ if a node is created.
+
+
+Example:
+
+ pmic0: da9062@58 {
+ compatible = "dlg,da9062";
+ reg = <0x58>;
+ interrupt-parent = <&gpio6>;
+ interrupts = <11 IRQ_TYPE_LEVEL_LOW>;
+ interrupt-controller;
+
+ watchdog {
+ compatible = "dlg,da9062-watchdog";
+ };
+
+ regulators {
+ DA9062_BUCK1: buck1 {
+ regulator-name = "BUCK1";
+ regulator-min-microvolt = <300000>;
+ regulator-max-microvolt = <1570000>;
+ regulator-min-microamp = <500000>;
+ regulator-max-microamp = <2000000>;
+ regulator-boot-on;
+ };
+ DA9062_LDO1: ldo1 {
+ regulator-name = "LDO_1";
+ regulator-min-microvolt = <900000>;
+ regulator-max-microvolt = <3600000>;
+ regulator-boot-on;
+ };
+ };
+ };
