From 51ded7cdf26deea7dd875047c2f005b81e80bdf4 Mon Sep 17 00:00:00 2001 From: Minghao Xue Date: Fri, 10 Jun 2022 16:58:26 +0800 Subject: [PATCH] dt-bindings: virtio: mmio: add optional wakeup-source property Some systems want to set the interrupt of virtio_mmio device as a wakeup source. On such systems, we'll use the existence of the "wakeup-source" property as a signal of requirement.
