| * 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. | ||
