From mboxrd@z Thu Jan 1 00:00:00 1970 From: thomas.abraham@linaro.org (Thomas Abraham) Date: Mon, 04 Jun 2012 08:16:31 +0530 Subject: [PATCH] ARM: S3C64XX: Add a new dma request id for device tree based dma channel lookup Message-ID: <1338777991-27194-1-git-send-email-thomas.abraham@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Commit 4972a80e16a2 (ARM: SAMSUNG: Add device tree support for pl330 dma engine wrappers) introduced a new member 'dt_dmach_prop' in the struct samsung_dma_info which is used to specify the dma channel number property as obtained from the device tree. It also introduced a new dma request id 'DMACH_DT_PROP' to indicate that a device tree node property represting the dma channel is available in 'struct samsung_dma_info'. Add dma request id 'DMACH_DT_PROP' in s3c64xx dma channel id list in order to maintain compatibility to the changes in the Samsung dma wrappper operations.
