Subject: [PATCH v3 1/3] dt-bindings: can-controller: add support for termination-gpios
Date: Wed, 18 Aug 2021 09:12:30 +0200 [thread overview]
Message-ID: <20210818071232.20585-2-o.rempel@pengutronix.de> (raw)
In-Reply-To: <20210818071232.20585-1-o.rempel@pengutronix.de>
Some boards provide GPIO controllable termination resistor. Provide
binding to make use of it.
