This patch set already tested on multi platforms: - AMD Seattle board; - Cavium Thunder board; - Huawei D02 board; - Qualcomm ARM64 platform
This version 10 patch set address some minor comments and collect ACKs and Reviewed-bys for v9:
- new Acks from Rafael, Olof, Grant, Lorenzo - new way to handle typdef phys_cpuid_t which suggested by Rafael, but no functional change - Remove if(!phys) for early ioremappings - Rework sleep function for ARM64 - Introduce linux/acpi_irq.h to hold acpi_irq_init() - Disable ACPI if not HW_REDUCED_ACPI compliant - Remove the doc of why ACPI on ARM
Thanks Hanjun
