* 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.
|
||||
|
||||

|
||||
|
||||
s5m8767_pmic@66 {
