Re: Shouldn't DT preserve pdev name and id to allow platform_match to work?

FWIW, I do not care about the physical address at all. This is just used 
by the of_dev_lookup function to get the proper instance for a device 
compatible type.
That's the only way for the OF_DEV_AUXDATA to work, but in theory you 
could do the same as soon as you provide the id. So OF_DEV_AUXDATA_ID 
could avoid it.

Since OF_DEV_AUXDATA_ID seems to be already dead before it even reaches 
the mainline, let's forget about that.
