1* Dialog Semiconductor DA9211/DA9213 Voltage Regulator
2
3Required properties:
4- compatible: "dlg,da9211" or "dlg,da9213".
5- reg: I2C slave address, usually 0x68.
6- interrupts: the interrupt outputs of the controller
7- regulators: A node that houses a sub-node for each regulator within the
8 device. Each sub-node is identified using the node's name, with valid
9 values listed below. The content of each sub-node is defined by the
10 standard binding for regulators; see regulator.txt.
11 BUCKA and BUCKB.
