Subject: [PATCH v2 0/4] MIPS DMA coherence fixes

Hi all,

This series fixes MIPS per-device DMA coherence support. It's mostly adjusting
Kconfig options.

The v1 series had some extra patches that fixing default coherency settings
for OF probing but I decided to send them as a dedicated series.

Thanks.

Jiaxun Yang (4):
  MIPS: Remove DMA_PERDEV_COHERENT
  MIPS: Always select ARCH_HAS_SETUP_DMA_OPS
  MIPS: Always select ARCH_HAS_SYNC_DMA_FOR_CPU for noncoherent
    platforms
  MIPS: c-r4k: Always install dma flush functions
