Current scmi drivers not work well with devlink. This patchset is a retry to address the issue in [1] which was a few months ago.
Current scmi devices are not created from device tree, they are created from a scmi_device_id entry of each driver with the protocol matches with the fwnode reg value, this means there could be multiple devices created for one fwnode, but the fwnode only has one device pointer.
This patchset is to do more checking before setting the device fwnode.
This may looks like hack, but seems no better way to make scmi works well with devlink.
