From mboxrd@z Thu Jan 1 00:00:00 1970 From: lee.jones@linaro.org (Lee Jones) Date: Fri, 3 May 2013 15:31:50 +0100 Subject: [PATCH 04/63] ARM: ux500: Supply MMC DMA configuration via Device Tree In-Reply-To: <1367591569-32197-1-git-send-email-lee.jones@linaro.org> References: <1367591569-32197-1-git-send-email-lee.jones@linaro.org> Message-ID: <1367591569-32197-5-git-send-email-lee.jones@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org When requesting a channel, a DMA client needs to pass some pieces of information such as; request channel, device type, channel type and direction etc. Normally we do this in the form of platform data, but when DT is enabled we need to pass it using the driver's bindings instead.
