Subject: [PATCH v2] regulator: dt-bindings: dlg,slg51000: Convert to DT schema
Convert the bindings for Dialog Semiconductor SLG51000 Voltage Regulator
to DT schema.
Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>
---
Changes in v2:
1. Mention that supplies are required, if the regulator is enabled.

-* Dialog Semiconductor SLG51000 Voltage Regulator
-
-Required properties:
-- compatible : Should be "dlg,slg51000" for SLG51000
-- reg : Specifies the I2C slave address.
-- xxx-supply: Input voltage supply regulator for ldo3 to ldo7.
- These entries are required if regulators are enabled for a device.
- An absence of these properties can cause the regulator registration to fail.
- If some of input supply is powered through battery or always-on supply then
- also it is required to have these parameters with proper node handle of always
- on power supply.
- vin3-supply: Input supply for ldo3
- vin4-supply: Input supply for ldo4
- vin5-supply: Input supply for ldo5
- vin6-supply: Input supply for ldo6
- vin7-supply: Input supply for ldo7
-
-Optional properties:
-- interrupt-parent : Specifies the reference to the interrupt controller.
-- interrupts : IRQ line information.
-- dlg,cs-gpios : Specify a valid GPIO for chip select
-
-Sub-nodes:
-- regulators : This node defines the settings for the regulators.
- The content of the sub-node is defined by the standard binding
- for regulators; see regulator.txt.
-
- The SLG51000 regulators are bound using their names listed below:
- ldo1
- ldo2
- ldo3
- ldo4
- ldo5
- ldo6
- ldo7
-
-Optional properties for regulators:
-- enable-gpios : Specify a valid GPIO for platform control of the regulator.
-
-Example:
- pmic: slg51000@75 {
- compatible = "dlg,slg51000";
- reg = <0x75>;
-
- regulators {
- ldo1 {
- regulator-name = "ldo1";
- regulator-min-microvolt = <2400000>;
- regulator-max-microvolt = <3300000>;
- };
-
- ldo2 {
- regulator-name = "ldo2";
- regulator-min-microvolt = <2400000>;
- regulator-max-microvolt = <3300000>;
- };
-
- ldo3 {
- regulator-name = "ldo3";
- regulator-min-microvolt = <1200000>;
- regulator-max-microvolt = <3750000>;
- };
-
- ldo4 {
- regulator-name = "ldo4";
- regulator-min-microvolt = <1200000>;
- regulator-max-microvolt = <3750000>;

- ldo5 {
- regulator-name = "ldo5";
- regulator-min-microvolt = <500000>;
- regulator-max-microvolt = <1200000>;
