Subject: [PATCH v1 1/3] dt-bindings: can-controller: add support for termination-gpios
Date: Mon, 16 Aug 2021 13:48:38 +0200	[thread overview]
Message-ID: <20210816114840.17502-1-o.rempel@pengutronix.de> (raw)

Some boards provide GPIO controllable termination resistor. Provide
binding to make use of it.
