[V3 PATCH 1/5] ACPI / scan: Parse _CCA and setup device coherency

2015-05-07 Thread Suravee Suthikulpanit
This patch implements support for ACPI _CCA object, which is introduced in ACPIv5.1, can be used for specifying device DMA coherency attribute. The parsing logic traverses device namespace to parse coherency information, and stores it in acpi_device_flags. Then uses it to call arch_setup_dma_ops()
