* Samsung S5M8767 Voltage and Current Regulator
The Samsung S5M8767 is a multi-function device which includes volatage 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.
- s5m8767,pmic-buck2-uses-gpio-dvs: 'buck2' can be controlled by gpio dvs.
- s5m8767,pmic-buck3-uses-gpio-dvs: 'buck3' can be controlled by gpio dvs.
- s5m8767,pmic-buck4-uses-gpio-dvs: 'buck4' can be controlled by gpio dvs.
Additional properties required if either of the optional properties are used:
- s5m8767,pmic-buck234-default-dvs-idx: Default voltage setting selected from
the possible 8 options selectable by the dvs gpios. The value of this
property should be between 0 and 7. If not specified or if out of range, the
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";
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 op_mode description.
- 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
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.
- LDOn
- valid values for n are 1 to 28
- Example: LDO0, LD01, LDO28
- BUCKn
- valid values for n are 1 to 9.
- Example: BUCK1, BUCK2, BUCK9
The bindings inside the regulator nodes use the standard regulator bindings
which are documented elsewhere.
Example:
s5m8767_pmic@66 {
compatible = "samsung,s5m8767-pmic";
reg = <0x66>;
