		* Samsung S5M8767 Voltage and Current Regulator
		Binding for Samsung S5M8767 regulator block
		===========================================

		The Samsung S5M8767 is a multi-function device which includes voltage and
		current regulators, rtc, charger controller and other sub-blocks. It is
		interfaced to the host controller using a i2c interface. Each sub-block is
		addressed by the host system using different i2c slave address. This document
		describes the bindings for 'pmic' sub-block of s5m8767.
		This is a part of device tree bindings for S5M family multi-function devices.
		More information can be found in bindings/mfd/sec-core.txt file.

		Required properties:
		- compatible: Should be "samsung,s5m8767-pmic".
		- reg: Specifies the i2c slave address of the pmic block. It should be 0x66.
		The S5M8767 device provide buck and LDO regulators.

		To register these with regulator framework instantiate under main device node
		a sub-node named "regulators" with more sub-nodes for each regulator using the
		common regulator binding documented in:
		- Documentation/devicetree/bindings/regulator/regulator.txt


		Required properties of the main device node (the parent!):
		- s5m8767,pmic-buck2-dvs-voltage: A set of 8 voltage values in micro-volt (uV)
		units for buck2 when changing voltage using gpio dvs. Refer to [1] below
		for additional information.

		Regulators: The regulators of s5m8767 that have to be instantiated should be
		included in a sub-node named 'regulators'. Regulator nodes included in this
		sub-node should be of the format as listed below.

		regulator_name {
		ldo1_reg: LDO1 {
		regulator-name = "VDD_ALIVE_1.0V";
		regulator-min-microvolt = <1100000>;
		regulator-max-microvolt = <1100000>;
		regulator-always-on;
		regulator-boot-on;
		op_mode = <1>; /* Normal Mode */
		};
		};
		The above regulator entries are defined in regulator bindings documentation
		except these properties:
		- op_mode: describes the different operating modes of the LDO's with
		power mode change in SOC. The different possible values are,
		0 - always off mode
		1 - on in normal mode
		2 - low power mode
		3 - suspend mode
		- s5m8767,pmic-ext-control-gpios: (optional) GPIO specifier for one
		GPIO controlling this regulator (enable/disable); This is
		valid only for buck9.

		The following are the names of the regulators that the s5m8767 pmic block
		supports. Note: The 'n' in LDOn and BUCKn represents the LDO or BUCK number
		as per the datasheet of s5m8767.

		Names of regulators supported by S5M8767 device:
		- LDOn
		- valid values for n are 1 to 28
		- Example: LDO1, LDO2, LDO28
		- BUCKn
		- valid values for n are 1 to 9.
		- Example: BUCK1, BUCK2, BUCK9
		Note: The 'n' in LDOn and BUCKn represents the LDO or BUCK number
		as per the datasheet of device.


		The bindings inside the regulator nodes use the standard regulator bindings
		which are documented elsewhere.
		Optional properties of the nodes under "regulators" sub-node:
		- op_mode: describes the different operating modes of the LDO's with
		power mode change in SOC. The different possible values are,
		0 - always off mode
		1 - on in normal mode
		2 - low power mode
		3 - suspend mode
		- s5m8767,pmic-ext-control-gpios: (optional) GPIO specifier for one
		GPIO controlling this regulator
		(enable/disable); This is valid only
		for buck9.
