1*4882a593SmuzhiyunDIO5632 regulators
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunRequired properties:
4*4882a593Smuzhiyun- compatible: "DIO5632"
5*4882a593Smuzhiyun- reg: I2C slave address
6*4882a593Smuzhiyun
7*4882a593SmuzhiyunOptional Subnode:
8*4882a593SmuzhiyunDevice supports two regulators OUTP and OUTN. A sub node within the
9*4882a593Smuzhiyun   device node describe the properties of these regulators. The sub-node
10*4882a593Smuzhiyun   names must be as follows:
11*4882a593Smuzhiyun	-For regulator outp, the sub node name should be "outp".
12*4882a593Smuzhiyun	-For regulator outn, the sub node name should be "outn".
13*4882a593Smuzhiyun
14*4882a593Smuzhiyun-enable-gpios:(active high, output) Regulators are controlled by the input pins.
15*4882a593Smuzhiyun   If it is connected to GPIO through host system then provide the
16*4882a593Smuzhiyun   gpio number as per gpio.txt.
17*4882a593Smuzhiyun
18*4882a593SmuzhiyunEach regulator is defined using the standard binding for regulators.
