Merge branch 'next/devel-dma-ops' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into next/dma
From Kukjin Kim <kgene.kim@samsung.com>: Here is updating DMA common operation for Samsung SoCs. Since some DMA client driver such as spi needs to change the configuration after dma_request() so this branch adds dma_config() can configure DMA transmit option which is included in dma_request() after that. Note, according to the changes, needs to update spi and ASoC drivers for Samsung SoCs and only got the ack from Mark Brown not Grant Likely and as I know, he is busy for moving. But I think, the spi change has no problem and it is simple. * 'next/devel-dma-ops' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung: ARM: SAMSUNG: Fix compiler warning in dma-ops.c file ASoC: follow the updated samsung DMA common operations spi/s3c64xx: Add the use of DMA config operation ARM: SAMSUNG: Add config() function in DMA common operations Signed-off-by: Arnd Bergmann <arnd@arndb.de>
