SubjectRe: [PATCH] dt-bindings: virtio: mmio: add optional virtio,wakeup property
Hi Krzysztof,

Thanks for your comment. First of all, which "generic wakeup-source
property" do you mean? Could you give an example? I find "wakeup-source"
property in several binding files. Are you pointing to this? As my
understanding, there is no standard naming rule about the property of
each driver right? Currently, there's no virtio-mmio driver using this.
Anyway, I can modify my patch, if you prefer "wakeup-source".

Regards,
Minghao
