1*4882a593SmuzhiyunMAXIM, MAX77686 pmic
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunThis device uses two drivers:
4*4882a593Smuzhiyun- drivers/power/pmic/max77686.c (for parent device)
5*4882a593Smuzhiyun- drivers/power/regulator/max77686.c (for child regulators)
6*4882a593Smuzhiyun
7*4882a593SmuzhiyunThis file describes the binding info for the PMIC driver.

9*4882a593SmuzhiyunTo bind the regulators, please read the additional binding info:
10*4882a593Smuzhiyun- doc/device-tree-bindings/regulator/max77686.txt
11*4882a593Smuzhiyun
12*4882a593SmuzhiyunRequired properties:
13*4882a593Smuzhiyun- compatible: "maxim,max77686"
14*4882a593Smuzhiyun- reg = 0x9
15*4882a593Smuzhiyun
16*4882a593SmuzhiyunWith those two properties, the pmic device can be used for read/write only.
17*4882a593SmuzhiyunTo bind each regulator, the optional regulators subnode should exists.
