I'm perfectly willing to extend it if you let me know what you think is 
needed, rather than just saying "switches and muxes".  What 
*specifically* would they need beyond what I proposed?

Give me something I can incorporate, then.  My gripe is when the 
feedback is "don't bother" based on unspecified problems with a 
configuration more complex than what it was intended to address (but 
still, AFAICT, not outside its ability to address).

We had a way to specify platform devices before, too.  If the device 
tree isn't worthwhile for i2c devices, why is it worthwhile for soc 
devices?  It seems to me that non-probable chips like i2c devices are 
precisely the kind of thing that the device tree is useful for.
