NAK. For one plat_* is not a valid name for dma-mapping operations. Second this needs a detailed explanation of the semantics and why they matter.

[PATCH V4 1/3] dma-mapping: Provide a default plat_device_is_coherent()

2017-09-14 Thread Huacai Chen
We will use plat_device_is_coherent() in generic cases, but it is MIPS-specific now. So we provide a default implementation. BTW, export the symbol hw_coherentio for MIPS if the caller of plat_device_is_coherent() is in a module. Cc: sta...@vger.kernel.org Signed-off-by: Huacai Chen --- arch/mi
