With all due respect, I consider Greg as THE reviewer for device/driver 
questions. Your earlier proposal to use platform devices was rejected by 
Greg, and we've lost an entire month in the process, so I am somewhat 
dubious on your proposal not to use a driver.

If you want a technical objection, let me restate what I already mentioned:

If you look at the hierarchy, we have

PCI device -> PCI driver
   soundwire_master_device0
      soundwire_slave(s) -> codec driver
   ...
   soundwire_master_deviceN
      soundwire_slave(s) -> codec driver

You have not explained how I could possibly deal with power management 
without having a driver for the master_device(s). The pm_ops need to be 
inserted in a driver structure, which means we need a driver. And if we 
need a driver, then we might as well have a real driver with .probe 
.remove support, driver_register(), etc.

I really don't see what's broken or unnecessary with these patches.

I would also kindly ask that you stop using exclamation marks and what I 
consider as hostile language. I've asked you multiple times, it's not 
professional, sorry.
