-Subject: [PATCH 16/93] ARM: asm: types: Introduce DMA_ADDR_T_64BIT
-
-dma_addr_t holds any valid DMA address. If the DMA API only uses 32-bit
-addresses, dma_addr_t need only be 32 bits wide.  Bus addresses, e.g., PCI BARs,
-may be wider than 32 bits, but drivers do memory-mapped I/O to ioremapped
-kernel virtual addresses, so they don't care about the size of the actual
-bus addresses.
-Also 32 bit ARM systems with LPAE enabled can use 64bit address space, but
-DMA still use 32bit address like in case of DRA7 and Keystone platforms.
-
-This is inspired from the Linux kernel types implementation[1]
