Subject: [PATCH V1 3/3] ARM: dts: sabreauto: Add flexcan support
Date: Wed, 24 Oct 2018 11:14:42 +0000 [thread overview]
Message-ID: <20181024111213.2724-4-qiangqing.zhang@nxp.com> (raw)
In-Reply-To: <20181024111213.2724-1-qiangqing.zhang@nxp.com>
From: Dong Aisheng <aisheng.dong@nxp.com>
The flexcan1 is pin conflict with fec. So we add a new dts file with
flexcan1 enabled with fec disabled for user to use.
