Subject: [PATCH v4 5/7] dt-bindings: regulator: bd9576 add FET ON-resistance for OCW
Date: Tue, 6 Apr 2021 10:14:04 +0300	[thread overview]
Message-ID: <34d37fcef80153b6c610826f885c0f6c36cdd93f.1617690965.git.matti.vaittinen@fi.rohmeurope.com> (raw)
In-Reply-To: <cover.1617690965.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.
