Subject: [PATCH 06/10] dma: imx-sdma: add terminate_all support
Date: Tue, 17 May 2016 12:48:52 +0900 [thread overview]
Message-ID: <1463456936-10634-7-git-send-email-jiada_wang@mentor.com> (raw)
In-Reply-To: <1463456936-10634-1-git-send-email-jiada_wang@mentor.com>
Implement device_terminate_all(), so that dmaengine_terminate_async()
can work.
