[RFC PATCH 5/7] dt-bindings: regulator: bd9576 add FET ON-resistance for OCW

From: Matti Vaittinen
Date: Thu Feb 11 2021 - 08:05:53 EST


BD9576MUF provides over-current protection and detection. Current is
measured as voltage loss over external FET. Allow specifying FET's on
resistance so current monitoring limits can be converted to voltages.
