However, current platform DMA code didn't support the M2M channels which were required for SPI (and IDE) peripherals. Ryan Mallon suggested that maybe we should integrate both M2M and M2P code under the dmaengine API. The purpose of this series is to do just that and convert all the existing users to use that new API. Patches 1-4 add dmaengine driver and convert the existing users to dmaengine API. The last patch adds DMA support for the SPI driver. I've been testing these on TS-7260 (ep9302) connected to SPI EEPROM, and Sim.One (ep9307) with mmc_spi and AC'97 audio. memcpy() testing has been done by running drivers/dma/dmatest.ko.
