From: Nicolin Chen Date: Thu, 14 Sep 2017 18:46:43 +0000 (-0700) Subject: dmaengine: imx-sdma: Correct src_addr_widths and directions X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f9d4a398f121b00f581da1428bff9b93d955452d;p=openwrt%2Fstaging%2Fblogic.git dmaengine: imx-sdma: Correct src_addr_widths and directions The driver already supports DMA_DEV_TO_DEV in sdma_config(), DMA_SLAVE_BUSWIDTH_2_BYTES and DMA_SLAVE_BUSWIDTH_1_BYTE in sdma_prep_slave_sg(). So this patch adds them to the lists.
