* Dialog Semiconductor DA9211/DA9213 Voltage Regulator
|
|
|
|
Required properties:
|
|
- compatible: "dlg,da9211" or "dlg,da9213".
|
|
- reg: I2C slave address, usually 0x68.
|
|
- interrupts: the interrupt outputs of the controller
|
|
- regulators: A node that houses a sub-node for each regulator within the
|
|
device. Each sub-node is identified using the node's name, with valid
|
|
values listed below. The content of each sub-node is defined by the
|
|
standard binding for regulators; see regulator.txt.
|
|
BUCKA and BUCKB.
|
|
|
|
Optional properties:
|
|
- enable-gpios: platform gpio for control of BUCKA/BUCKB.
|
|
- Any optional property defined in regulator.txt
|
|

Example 1) DA9211
|
|
|
|
pmic: da9211@68 {
|
|
compatible = "dlg,da9211";
|
|
reg = <0x68>;
|
|
interrupts = <3 27>;
|
|
|
|
regulators {
|
|
BUCKA {
|
|
regulator-name = "VBUCKA";
|
|
regulator-min-microvolt = < 300000>;
|
|
regulator-max-microvolt = <1570000>;
|
|
regulator-min-microamp = <2000000>;
|
|
regulator-max-microamp = <5000000>;
|
|
enable-gpios = <&gpio 27 0>;
|
|
};
|
|
BUCKB {
|
|
regulator-name = "VBUCKB";
|
|
regulator-min-microvolt = < 300000>;
|
|
