* 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

Qualcomm Resource Power Manager (RPM) over SMD
QCOM SMD RPM REGULATOR
This driver is used to interface with the Resource Power Manager (RPM) found in
various Qualcomm platforms. The RPM allows each component in the system to vote
for state of the system resources, such as clocks, regulators and bus
frequencies.
The Qualcomm RPM over SMD regulator is modelled as a subdevice of the RPM.
Because SMD is used as the communication transport mechanism, the RPM resides as
a subnode of the SMD. As such, the SMD-RPM regulator requires that the SMD and
RPM nodes be present.

Qualcomm Resource Power Manager (RPM) over SMD
This driver is used to interface with the Resource Power Manager (RPM) found in
various Qualcomm platforms. The RPM allows each component in the system to vote
for state of the system resources, such as clocks, regulators and bus
frequencies.
The SMD information for the RPM edge should be filled out. See qcom,smd.txt for
the required edge properties. All SMD related properties will reside within the
RPM node itself.
= SUBDEVICES
The RPM exposes resources to its subnodes. The rpm_requests node must be
present and this subnode may contain children that designate regulator
resources.
