Subject: [PATCH v2 3/4] can: m_can: Update documentation to mention new fixed transceiver binding
Date: Mon, 24 Jul 2017 18:05:20 -0500	[thread overview]
Message-ID: <20170724230521.1436-4-fcooper@ti.com> (raw)
In-Reply-To: <20170724230521.1436-1-fcooper@ti.com>

Add information regarding fixed transceiver binding. This is especially
important for MCAN since the IP allows CAN FD mode to run significantly
faster than what most transceivers are capable of.
