Subject: [PATCH 3/5] dmaengine: sprd: Move DMA request mode and interrupt type into head file
Date: Tue, 10 Apr 2018 15:46:05 +0800	[thread overview]
Message-ID: <c31db49672ba765881dc8329f5681a891cc615ba.1523346135.git.baolin.wang@linaro.org> (raw)
In-Reply-To: <abdda9da96185f764d58bbf61db9010d0f72d1b3.1523346135.git.baolin.wang@linaro.org>

From: Eric Long <eric.long@spreadtrum.com>

This patch will move the Spreadtrum DMA request mode and interrupt type
into one head file for user to configure. And other special SPRD DMA
configurations will be added in the following patches.
