The default cache operations for ARM64 were changed during 3.15. To use coherent operations a "dma-coherent" device tree property is required. If that property is not present in the device tree node then the non-coherent operations are assigned for the device. Add support to the ccp driver to assign the AXI DMA cache settings based on whether the "dma-coherent" property is present in the device node. If present, use settings that work with the caches. If not present, use settings that do not look at the caches. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> |
