Subject: [PATCH 0/7] MIPS DMA coherence fixes


Jiaxun Yang (7):
  MIPS: Remove DMA_PERDEV_COHERENT
  MIPS: Always select ARCH_HAS_SYNC_DMA_FOR_CPU for noncoherent
    platforms
  MIPS: c-r4k: Always install dma flush functions
  dma-mapping: Always provide dma_default_coherent
  dma-mapping: Provide CONFIG_ARCH_DMA_DEFAULT_COHERENT
  riscv: Select ARCH_DMA_DEFAULT_COHERENT
  of: address: Use dma_default_coherent to determine default coherency
