-* Samsung S5M8767 Voltage and Current Regulator
-
-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.
-
-Required properties:
-- compatible: Should be "samsung,s5m8767-pmic".
-- reg: Specifies the i2c slave address of the pmic block. It should be 0x66.
-
-- 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.
-
-- s5m8767,pmic-buck3-dvs-voltage: A set of 8 voltage values in micro-volt (uV)
- units for buck3 when changing voltage using gpio dvs. Refer to [1] below
- for additional information.
-
-- s5m8767,pmic-buck4-dvs-voltage: A set of 8 voltage values in micro-volt (uV)
- units for buck4 when changing voltage using gpio dvs. Refer to [1] below
- for additional information.
-
-- s5m8767,pmic-buck-ds-gpios: GPIO specifiers for three host gpio's used
- for selecting GPIO DVS lines. It is one-to-one mapped to dvs gpio lines.
-
-[1] If none of the 's5m8767,pmic-buck[2/3/4]-uses-gpio-dvs' optional
- property is specified, the 's5m8767,pmic-buck[2/3/4]-dvs-voltage'
- property should specify atleast one voltage level (which would be a
- safe operating voltage).
-
- If either of the 's5m8767,pmic-buck[2/3/4]-uses-gpio-dvs' optional
- property is specified, then all the eight voltage values for the
- 's5m8767,pmic-buck[2/3/4]-dvs-voltage' should be specified.
-
-Optional properties:
-- interrupt-parent: Specifies the phandle of the interrupt controller to which
- the interrupts from s5m8767 are delivered to.
-- interrupts: Interrupt specifiers for two interrupt sources.
- - First interrupt specifier is for 'irq1' interrupt.
- - Second interrupt specifier is for 'alert' interrupt.

- default value of this property is set to 0.
-
-- s5m8767,pmic-buck-dvs-gpios: GPIO specifiers for three host gpio's used
- for dvs. The format of the gpio specifier depends in the gpio controller.
-
-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";

- - Example: LDO1, LDO2, LDO28

-which are documented elsewhere.
