Please upstream bindings for the bus devices and extend the example here
with these devices.

The set of synthetic devices that reside on the bus isn't fixed, and
they don't require description neither in ACPI nor in DT as
the devices negotiate their MMIO regions through the hyperv driver.

Perhaps, it is not as much bus as expected by the YAML files.

OK, then this is not really a bus from the bindings point of view. It is
a device schema which should end with additionalProperties: false.

If you have report about that pinctrl-0, it means you have undocumented
properties in your DTS. Maybe that's the dma-coherence you mentioned in
the commit msg.
