* Powerventure Semiconductor PV88060 Voltage Regulator
|
||||
|
||||
Required properties:
|
||||
- compatible: "pvs,pv88060".
|
||||
- reg: I2C slave address, usually 0x49.
|
||||
- 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.
|
||||
BUCK1, LDO1, LDO2, LDO3, LDO4, LDO5, LDO6, LDO7, SW1, SW2, SW3, SW4,
|
||||
SW5, and SW6.
|
||||
|
||||
Optional properties:
|
||||
- Any optional property defined in regulator.txt
