Merge tag 's3c64xx-dmaengine' of git://git.kernel.org/pub/scm/linux/k…

From Tomasz Figa via Mark Brown:
ARM: s3c64xx: Convert to dmaengine

This series of commits from Tomasz converting s3c64xx to use dmaengine
rather than the old s3c-dma API missed the v3.13 merge window - Kukjin
said that he'd applied it (which should mean it's OK from a review point
of view) but it didn't make it into -next or a pull request.

Since a s3c64xx based system is one of my primary development platforms
it'd be really helpful if I could merge this into both ASoC and SPI,
I've got some patches for ASoC ready to go converting to use dmaengine
directly which help with multiplatform and there's some other dmaengine
work for SPI in progress too.  I've therefore made this signed tag, it'd
be great if it could be merged into both arm-soc and those two trees.

* tag 's3c64xx-dmaengine' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/misc:
  spi: s3c64xx: Always select S3C64XX_PL080 when ARCH_S3C64XX is enabled
  clk: samsung: s3c64xx: Remove clock aliases of old DMA driver
  ARM: s3c64xx: Remove legacy DMA driver
  clk: samsung: s3c64xx: Add aliases for DMA clocks
  ARM: s3c64xx: Add support for DMA using generic amba-pl08x driver
  spi: s3c64xx: Do not require legacy DMA API in case of S3C64XX
