Subject: [PATCH v5 1/7] can: etas_es58x: add devlink support
Date: Thu, 1 Dec 2022 02:46:52 +0900 [thread overview]
Message-ID: <20221130174658.29282-2-mailhol.vincent@wanadoo.fr> (raw)
In-Reply-To: <20221130174658.29282-1-mailhol.vincent@wanadoo.fr>
Add basic support for devlink at the device level. The callbacks of
struct devlink_ops will be implemented next.
