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
