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"
Minghao Xue (2): dt-bindings: virtio: mmio: add optional wakeup-source property virtio_mmio: add support to set IRQ of a virtio device as wakeup source
