Subject: [PATCH v3 02/14] mfd/regulator: dt-bindings: max77686: Document
 of_compatible for regulator

Document new required property for regulator driver: of_compatible. The
property allows MFD core to bind the driver to node with regulators and
this simplifies parsing regulators init data from DTS
