In the case platform_device is the OF device your controller gets probed
on.

My thinking on this is that drivers should not be directly creating
sdw_master_device but it should be done by core as this device is for
core to use and handle. Ideally I would love that sdw_master_device is
created/handled by core, preferably this be handled as part of
sdw_add_bus_master().

But Pierre is trying to solve the limitation of the devices given by
ACPI and trying to add sdw_master_driver to handle that. I am not
convinced that we should do that.
