Binding for Maxim MAX77802 regulators
|
|
|
|
This is a part of device tree bindings of MAX77802 multi-function device.
|
|
More information can be found in bindings/mfd/max77802.txt file.
|
|
|
|
The MAX77802 PMIC has 10 high-efficiency Buck and 32 Low-dropout (LDO)
|
|
regulators that can be controlled over I2C.
|
|
|
|
Following properties should be present in main device node of the MFD chip.
|
|
|
|
Optional node:
|
|
- regulators : The regulators of max77802 have to be instantiated
|
|
under subnode named "regulators" using the following format.
|
|
|
|
regulator-name {
|
|
standard regulator constraints....
|
|
};
|
|
refer Documentation/devicetree/bindings/regulator/regulator.txt
|
|
|
|
The regulator node name should be initialized with a string to get matched
|
|
with their hardware counterparts as follow. The valid names are:
|
|
|
|
-LDOn : for LDOs, where n can lie in ranges 1-15, 17-21, 23-30
|
|
and 32-35.
|
|
example: LDO1, LDO2, LDO35.
|
|
-BUCKn : for BUCKs, where n can lie in range 1 to 10.
|
|
example: BUCK1, BUCK5, BUCK10.
|
|
Example:
|
|
|
|
max77802@09 {
|
|
compatible = "maxim,max77802";
|
|
interrupt-parent = <&wakeup_eint>;
|
|
interrupts = <26 0>;
|
|
reg = <0x09>;
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
|
|

|

|
|
regulator-max-microvolt = <1900000>;
|
|

|
|
};
|
|
|
|

|
|

|

|
