Subject: [PATCH v2 12/35] nds32: DMA mapping API
Date: Mon, 27 Nov 2017 20:27:59 +0800 [thread overview]
Message-ID: <171cd2b4ea3795908afa6d34f5ba237d1552a807.1511785528.git.green.hu@gmail.com> (raw)

In-Reply-To: <cover.1511785528.git.green.hu@gmail.com>
From: Greentime Hu <greentime@andestech.com>
This patch adds support for the DMA mapping API. It uses dma_map_ops for
flexibility.
