Subject: [PATCH v6 5/6] dt-bindings: can: m_can: Document new can transceiver binding
Date: Fri, 22 Dec 2017 19:01:27 +0530 [thread overview]
Message-ID: <1513949488-13026-6-git-send-email-faiz_abbas@ti.com> (raw)
In-Reply-To: <1513949488-13026-1-git-send-email-faiz_abbas@ti.com>
From: Franklin S Cooper Jr <fcooper@ti.com>
Add information regarding can-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.
