* Maxim MAX8998, National/TI LP3974 multi-function device
The Maxim MAX8998 is a multi-function device which includes voltage/current
regulators, real time clock, battery charging controller and several
other sub-blocks. It is interfaced using an I2C interface. Each sub-block
is addressed by the host system using different i2c slave address.
PMIC sub-block
--------------
The PMIC sub-block contains a number of voltage and current regulators,
with controllable parameters and dynamic voltage scaling capability.
In addition, it includes a real time clock and battery charging controller
as well. It is accessible at I2C address 0x66.
Required properties:
- compatible: Should be one of the following:
- "maxim,max8998" for Maxim MAX8998
- "national,lp3974" or "ti,lp3974" for National/TI LP3974.
- reg: Specifies the i2c slave address of the pmic block. It should be 0x66.
Optional properties:
- interrupts: Interrupt specifiers for two interrupt sources.
- First interrupt specifier is for main interrupt.
- Second interrupt specifier is for power-on/-off interrupt.
- max8998,pmic-buck1-dvs-gpios: GPIO specifiers for two host gpios used
for buck 1 dvs. The format of the gpio specifier depends on the gpio
controller.
- max8998,pmic-buck2-dvs-gpio: GPIO specifier for host gpio used
for buck 2 dvs. The format of the gpio specifier depends on the gpio
controller.
- max8998,pmic-buck1-default-dvs-idx: Default voltage setting selected from
the possible 4 options selectable by the dvs gpios. The value of this
property should be 0, 1, 2 or 3. If not specified or out of range,
a default value of 0 is taken.
- max8998,pmic-buck2-default-dvs-idx: Default voltage setting selected from
the possible 2 options selectable by the dvs gpios. The value of this
property should be 0 or 1. If not specified or out of range, a default
value of 0 is taken.
- max8998,pmic-buck-voltage-lock: If present, disallows changing of
preprogrammed buck dvfs voltages.
Additional properties required if max8998,pmic-buck1-dvs-gpios is defined:
- max8998,pmic-buck1-dvs-voltage: An array of 4 voltage values in microvolts
for buck1 regulator that can be selected using dvs gpio.
Additional properties required if max8998,pmic-buck2-dvs-gpio is defined:
- max8998,pmic-buck2-dvs-voltage: An array of 2 voltage values in microvolts
for buck2 regulator that can be selected using dvs gpio.
Regulators: All the regulators of MAX8998 to be instantiated shall be
listed in a child node named 'regulators'. Each regulator is represented
by a child node of the 'regulators' node.
regulator-name {
/* standard regulator bindings here */
};
Following regulators of the MAX8998 PMIC block are supported. Note that
the 'n' in regulator name, as in LDOn or BUCKn, represents the LDO or BUCK
number as described in MAX8998 datasheet.
- LDOn
- valid values for n are 2 to 17
- Example: LDO2, LDO10, LDO17
- BUCKn
- valid values for n are 1 to 4.
- Example: BUCK1, BUCK2, BUCK3, BUCK4
- ENVICHG: Battery Charging Current Monitor Output. This is a fixed
voltage type regulator
- ESAFEOUT1: (ldo19)
- ESAFEOUT2: (ld020)
- CHARGER: main battery charger current control
Standard regulator bindings are used inside regulator subnodes. Check
Documentation/devicetree/bindings/regulator/regulator.txt
for more details.

pmic@66 {
compatible = "maxim,max8998-pmic";
reg = <0x66>;

Texas Instruments TWL family
The TWLs are Integrated Power Management Chips.
Some version might contain much more analog function like
USB transceiver or Audio amplifier.
These chips are connected to an i2c bus.
Required properties:
- compatible : Must be "ti,twl4030";
For Integrated power-management/audio CODEC device used in OMAP3
based boards
- compatible : Must be "ti,twl6030";
For Integrated power-management used in OMAP4 based boards
- interrupts : This i2c device has an IRQ line connected to the main SoC
- interrupt-controller : Since the twl support several interrupts internally,
it is considered as an interrupt controller cascaded to the SoC one.
- #interrupt-cells = <1>;
Optional node:
- Child nodes contain in the twl. The twl family is made of several variants
that support a different number of features.
The children nodes will thus depend of the capability of the variant.
Example:
/*
* Integrated Power Management Chip
* https://www.ti.com/lit/ds/symlink/twl6030.pdf
*/
twl@48 {
compatible = "ti,twl6030";
