Nit: Since this patch also mentions other virtio devices, the subject title should be updated to reflect that rather than only mentioning the RTC. > diff --git a/doc/develop/driver-model/virtio.rst > b/doc/develop/driver-model/virtio.rst > index e5da9f430..211304706 100644 > --- a/doc/develop/driver-model/virtio.rst > +++ b/doc/develop/driver-model/virtio.rst > @@ -28,7 +28,7 @@ queues configuration and buffer transfers are nearly > identical.

Since u-boot supports more virtio drivers now and likely even more in the future, I'm wondering if we should present them as a bulleted list for better clarity, rather than listing them inline in a sentence.
