* 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.
|
||||
BUCK1, BUCK2, and BUCK3.
