This patch set adds DT support for the MFD core of the da9055 PMIC, and adds
the accompanying DT binding documentation for the device.

+* Dialog DA9055 Power Management Integrated Circuit (PMIC)
+
+DA9055 consists of a large and varied group of sub-devices (I2C Only):
+
+Device Supply Names Description
+------ ------------ -----------
+da9055-gpio : : GPIOs
+da9055-regulator : : Regulators
+da9055-onkey : : On key
+da9055-rtc : : RTC
+da9055-hwmon : : ADC
+da9055-watchdog : : Watchdog
+
+The CODEC device in DA9055 has a separate, configurable I2C address and so
+is instantiated separately from the PMIC.
+
+For details on accompanying CODEC I2C device, see the following:
+Documentation/devicetree/bindings/sound/da9055.txt
+
+======
+
+Required properties:
+- compatible : Should be "dlg,da9055-pmic"
+- reg: Specifies the I2C slave address (defaults to 0x5a but can be modified)
+- interrupt-parent: Specifies the phandle of the interrupt controller to which
+ the IRQs from da9055 are delivered to.
+- interrupts: IRQ line info for da9055 chip.
+- interrupt-controller: da9055 has internal IRQs (has own IRQ domain).
+- #interrupt-cells: Should be 1, is the local IRQ number for da9055.
+
+Sub-nodes:
+- regulators : Contain the regulator nodes. The DA9055 regulators are
+ bound using their names as listed below:
+
+ buck1 : regulator BUCK1
+ buck2 : regulator BUCK2
+ ldo1 : regulator LDO1
+ ldo2 : regulator LDO2
+ ldo3 : regulator LDO3
+ ldo4 : regulator LDO4
+ ldo5 : regulator LDO5
+ ldo6 : regulator LDO6
+
+ The bindings details of individual regulator device can be found in:
+ Documentation/devicetree/bindings/regulator/regulator.txt
+
+
+Example:
+
+ pmic: da9055-pmic@5a {
+ compatible = "dlg,da9055-pmic";
+ reg = <0x5a>;
+ interrupt-parent = <&intc>;
+ interrupts = <5 0x8>;
+ interrupt-controller;
+ #interrupt-cells = <1>;
+
+ regulators {
+ buck1: BUCK1 {
+ regulator-min-microvolt = <725000>;
+ regulator-max-microvolt = <2075000>;
+ };
+
+ buck2: BUCK2 {
+ regulator-min-microvolt = <925000>;
+ regulator-max-microvolt = <2500000>;
+ };
+ ldo1: LDO1 {
+ regulator-min-microvolt = <900000>;
+ regulator-max-microvolt = <3300000>;
+ };
+ };
+ };

Patch looks okay to me, but needs an Ack from the DT guys.
