ACPI: ARM Performance Monitoring Unit Table (APMT) initial support ARM Performance Monitoring Unit Table describes the properties of PMU support in ARM-based system. The APMT table contains a list of nodes, each represents a PMU in the system that conforms to ARM CoreSight PMU architecture. The properties of each node include information required to access the PMU (e.g. MMIO base address, interrupt number) and also identification. For more detailed information, please refer to the specification below: * APMT: https://developer.arm.com/documentation/den0117/latest * ARM Coresight PMU: https://developer.arm.com/documentation/ihi0091/latest The initial support adds the detection of APMT table and generic infrastructure to create platform devices for ARM CoreSight PMUs. Similar to IORT the root pointer of APMT is preserved during runtime and each PMU platform device is given a pointer to the corresponding APMT node.

ACPI: Move AMBA bus scan handling into arm64 specific directory Commit fcea0ccf4fd7 ("ACPI: bus: Consolidate all arm specific initialisation into acpi_arm_init()") moved all of the ARM-specific initialization into acpi_arm_init(). However, acpi_amba.c being outside of drivers/acpi/arm64 got ignored and hence acpi_amba_init() was not moved into acpi_arm_init(). Move the AMBA platform bus support into arm64 specific folder and make acpi_amba_init() part of acpi_arm_init(). Signed-off-by: Sudeep Holla <sudeep.holla@arm.com> Signed-off-by: Rafael J.

ACPI: bus: Consolidate all arm specific initialisation into acpi_arm_init() Move all of the ARM-specific initialization into one function namely acpi_arm_init(), so it is not necessary to modify/update bus.c every time a new piece of it is added.

ACPI: scan: Support multiple DMA windows with different offsets In DT systems configurations, of_dma_get_range() returns struct bus_dma_region DMA regions; they are used to set-up devices DMA windows with different offset available for translation between DMA address and CPU address. In ACPI systems configuration, acpi_dma_get_range() does not return DMA regions yet and that precludes setting up the dev->dma_range_map pointer and therefore DMA regions with multiple offsets. Update acpi_dma_get_range() to return struct bus_dma_region DMA regions like of_dma_get_range() does. After updating acpi_dma_get_range(), acpi_arch_dma_setup() is changed for ARM64, where the original dma_addr and size are removed as these arguments are now redundant, and pass 0 and U64_MAX for dma_base and size of arch_setup_dma_ops; this is a simplification consistent with what other ACPI architectures also pass to iommu_setup_dma_ops().
