Subject: [PATCH v2 11/14] MIPS: Malta: Use syscon-reboot driver to reboot
Date: Mon, 19 Sep 2016 22:21:28 +0100 [thread overview]
Message-ID: <20160919212132.28893-12-paul.burton@imgtec.com> (raw)
In-Reply-To: <20160919212132.28893-1-paul.burton@imgtec.com>
Make use of the generic syscon-reboot driver to reboot the Malta board,
reducing the amount of platform code it requires.
Signed-off-by: Paul Burton <paul.burton@imgtec.com>
