Subject: [RFC PATCH v3 5/7] dt-bindings: regulator: bd9576 add FET ON-resistance for OCW
Date: Thu, 11 Mar 2021 12:23:33 +0200	[thread overview]
Message-ID: <6793280eb1a3376a1aa4d408a8931202050c828d.1615454845.git.matti.vaittinen@fi.rohmeurope.com> (raw)
In-Reply-To: <cover.1615454845.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.
