[PATCH V1] regulator: pv88080: new regulator driver

From: James Bans
Date: Thu Apr 14 2016 - 03:58:44 EST


From: James Ban <James.Ban.opensource@xxxxxxxxxxx>

This is the driver for the Powerventure PV88080 BUCKs regulator.
It communicates via an I2C bus to the device.

Signed-off-by: James Ban <James.Ban..opensource@xxxxxxxxxxx>

+* Powerventure Semiconductor PV88080 Voltage Regulator

+Required properties:
+- compatible: "pvs,pv88080".
+- 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.
