From mboxrd@z Thu Jan 1 00:00:00 1970 From: Subject: [PATCH 0/2] dmaengine: mtk-hsdma: add support for Mediatek High-Speed DMA controller on MT7623 SoC Date: Mon, 15 May 2017 14:59:25 +0800 Message-ID: Mime-Version: 1.0 Content-Type: text/plain Return-path: Sender: linux-kernel-owner@vger.kernel.org To: dan.j.williams@intel.com, vinod.koul@intel.com, robh+dt@kernel.org, mark.rutland@arm.com Cc: dmaengine@vger.kernel.org, devicetree@vger.kernel.org, linux-mediatek@lists.infradead.org, linux-arm-kernel@lists.infradead.org, linux-kernel@vger.kernel.org, keyhaede@gmail.com, Sean Wang List-Id: linux-mediatek@lists.infradead.org From: Sean Wang This patchset introduces support for Mediatek High-Speed DMA controller (MTK-HSDMA) Currently, the driver is already tested successfully with dmatest module on MT7623 SoC. MTK-HSDMA on MT7623 SoC has the single channel which is dedicated to memory-to-memory transfer through ring-based descriptor management. Even though there is only one physical channel available inside HSDMA, the driver is extended to the support for multiple virtual channels processing simultaneously in round-round way by means of the feature DMA_VIRTUAL_CHANNELS.
