This patch series includes following modifications: 1) remove redundant code 2) add coherent buffers 3) remove multiple channel requests and releases For more info please look into particular commit messages. I have tested my patches on Exynos 4412(with PL330 DMA) platform with S5C73M3 driver(firmware upload via SPI). This patch series depends on: [1] - https://lkml.org/lkml/2013/8/11/79 [2] - http://www.kernelhub.org/?msg=323408&p=2 When other SAMSUNG platforms will support DMA generic operations then my patches 1-4,6 can be applied. This is only proof of concept so any comments are welcome.
