virtio_mmio: add ACPI probing (38c4ab8e) · Commits · 戴 / test

Added the match table and pointers for ACPI probing to the driver. This uses the same identifier for virt devices as being used for qemu ARM64 ACPI support. http://git.linaro.org/people/shannon.zhao/qemu.git/commit/d0bf1955a3ecbab4b51d46f8c5dda02b7e14a17e Signed-off-by:
