Re: [PATCH 1/8] soundwire: bus_type: add master_device/driver support

Were the above lines agreed or not? Do you see driver for master devices
or not? Greg was okay with as well as these patches but I am not okay
with the driver part for master, so I would like to see that removed.

Different reviewers can have different reasons.. I have given bunch of
reasons here, BUT I have not seen a single technical reason why this
cannot be done.

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.

Regards
-Pierre
