* Powerventure Semiconductor PV88090 Voltage Regulator
|
||||
|
||||
Required properties:
|
||||
- compatible: "pvs,pv88090".
|
||||
- reg: I2C slave address, usually 0x48.
|
||||
- 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, BUCK2, BUCK3, LDO1, and LDO2.
|
||||
|
||||
Optional properties:
|
||||
- Any optional property defined in regulator.txt
