Subject: [PATCH 0/3] Use dma_mmap_coherent to support IOMMU mapper

There is a dma_mmap_coherent() API in some architectures.  This API
provides a mmap function for memory allocated by dma_alloc_coherent().
Some drivers mmap a dma_addr_t returned by dma_alloc_coherent() as a
physical address.  But such drivers do not work correctly when IOMMU
mapper is used.

Hideki EIRAKU (3):
  ARM: dma-mapping: define ARCH_HAS_DMA_MMAP_COHERENT
  media: videobuf2-dma-contig: use dma_mmap_coherent if available
  fbdev: sh_mobile_lcdc: use dma_mmap_coherent if available
