Hi Rob,
> Subject: [PATCH V9 01/10] dt-bindings: remoteproc: convert imx rproc
> bindings to json-schema
Do you have time to give a look and including
https://patchwork.kernel.org/project/linux-remoteproc/
patch/1611191015-22584-3-git-send-email-peng.fan@nxp.com/
If could get your R-b or A-b tag, we could have the whole patchset
merge into remoteproc tree.
Thanks,
Peng.

We might need to map an region multiple times, becaue the region might
be shared between remote processors, such i.MX8QM with dual M4 cores.
So use devm_ioremap, not devm_ioremap_resource.

The hook is used to parse memory-regions and load resource table
from the address the remote processor published.

vdev regions are vdev0vring0, vdev0vring1, vdevbuffer and similar.
