* Powerventure Semiconductor PV88080 Voltage Regulator
Required properties:
- compatible: "pvs,pv88080".
- reg: I2C slave address, usually 0x49.
- compatible: Must be one of the following, depending on the
silicon version:
- "pvs,pv88080" (DEPRECATED)
- "pvs,pv88080-aa" for PV88080 AA or AB silicon
- "pvs,pv88080-ba" for PV88080 BA or BB silicon
NOTE: The use of the compatibles with no silicon version is deprecated.
- 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.
