This patchset is to add memcpy interface for imx-sdma, besides,to support dmatest and enable config by default, so that could test dma easily without any other device support such as uart/audio/spi...
Change from v1: 1. remove bus_width check for memcpy since only max bus width needed for memcpy case to speedup copy. 2. remove DMATEST support patch, since DMATEST is a common memcpy case. 3. split to single patch for SDMA_BD_MAX_CNT instead of '0xffff' 4. move sdma_config_ownership() from alloc_chan into sdma_prep_memcpy. 5. address some minor review comments.
Robin Gong (3): dmaengine: imx-sdma: add SDMA_BD_MAX_CNT to replace '0xffff' dmaengine: imx-sdma: add memcpy interface ARM: configs: imx_v6_v7_defconfig: add DMATEST support
