Subject: [PATCH 5/7] ARM: STi: DT: STiH407: Add FDMA driver and xbar driver dt nodes.
Date: Wed,  8 Jul 2015 17:11:26 +0100	[thread overview]
Message-ID: <1436371888-27863-6-git-send-email-peter.griffin@linaro.org> (raw)
In-Reply-To: <1436371888-27863-1-git-send-email-peter.griffin@linaro.org>

These nodes are required to get the fdma and xbar driver working
on STiH407 based silicon.
