[PATCH v2 0/2] virtio_mmio: add support to set IRQ of a virtio device as wakeup source

[Minghao Xue]

Hi,
Some systems want to set the interrupt of virtio_mmio device as a wakeup source of system.
This patch series add support for such use case. And it can be enbaled by adding "wakeup-source" property to the device tree.

Patch 1: Add an optional "wakeup-source" property into binding file of virtio_mmio device.
Patch 2: Set IRQ of virtio_mmio device as wakeup source in virtqueue initialization, if "wakeup-source" is set in the device tree.

Version 2 changes (mostly feedback from Krzysztof Kozlowski)
-rename property from "virtio,wakeup" to "wakeup-source"
