Subject: [PATCH v8 07/10] dt-bindings: regulator: bd9576 add FET ON-resistance for OCW
Date: Mon, 19 Apr 2021 14:50:58 +0300
Message-ID: <7a8ee942001f4b407d33eb7c1e6886936061635d.1618832466.git.matti.vaittinen@fi.rohmeurope.com> (raw)
In-Reply-To: <cover.1618832466.git.matti.vaittinen@fi.rohmeurope.com>

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.
