[PATCH v2 0/5] dmaengine: convert dw_dmac/spear13xx to generic binding

Hi everyone,

I'm rather embarrassed to have sent yet another patch series
to the wrong mailing list address, this now goes to the
correct linux-arm-kernel list, so please comment here,
not on the first version. I have also made some smaller
changes and updated the DT bindings where I extended
the drivers. I also uploaded the git branch to the
spear/dma branch of

This is my attempt to convert the spear platform and the dw_dmac to
the generic device tree binding for DMA, so that we don't get
a release with the broken version. I'm pretty sure that this
has bugs, but it's as good as I could do without access to
hardware or specs.

Please review and comment,


Arnd Bergmann (5):
  dmaengine: dw_dmac: move to generic DMA binding
  spi: pl022: use generic DMA slave configuration if possible
  serial: pl011: use generic DMA slave configuration if possible
  ata: arasan: remove the need for platform_data
  ARM: SPEAr13xx: Pass generic DW DMAC platform data from DT
