From mboxrd@z Thu Jan 1 00:00:00 1970 From: Nicolin Chen Subject: [PATCH v4 0/4] Add dual-fifo mode support of i.MX ssi Date: Thu, 31 Oct 2013 21:44:12 +0800 Message-ID: Mime-Version: 1.0 Content-Type: text/plain Return-path: Sender: linux-doc-owner@vger.kernel.org To: timur@tabi.org, shawn.guo@linaro.org, broonie@kernel.org, s.hauer@pengutronix.de Cc: linux-arm-kernel@lists.infradead.org, devicetree@vger.kernel.org, linux-doc@vger.kernel.org, linux-kernel@vger.kernel.org, dmaengine@vger.kernel.org, linuxppc-dev@lists.ozlabs.org, alsa-devel@alsa-project.org, rob.herring@calxeda.com, mark.rutland@arm.com, swarren@wwwdotorg.org, pawel.moll@arm.com, ijc+devicetree@hellion.org.uk List-Id: devicetree@vger.kernel.org Changelog v4: * PATCH-3: Drop useless register configuration. * * Nothing changes for the other three patches v3: * PATCH-1: Add comments to indicate the end of v1 and v2 array. * PATCH-3: Use better way to keep watermark as even number. * * Nothing changes for PATCH-2 and PATCH-4 v2: * Instead of adding rogue scripts to current SDMA driver based on firmware * V1, we define the new SDMA firmware as version 2 and bisect the PATCH-1 * to two patches: The first is to add version check code to the SDMA driver; * And the second is to add SSI dual FIFO DMATYPE. * * Nothing changes for the last two patches. v1: * SSI can reduce hardware overrun/underrun possibility when using dual * fifo mode. To support this mode, we need to first update sdma sciprt * list, and then enable dual fifo BIT in SSI driver, and last update DT * bindings of i.MX series. * * ! This series of patches has a direct dependency between them. When * ! applying them, we need to apply to one single branch. Otherwise, * ! it would break currect branches.
