regarding cpm_uart and platform_bus_type

Hi all,

I was wondering, since arch/powerpc is now based on device trees,  
shouldn't the cpm_uart driver (or at least a branch of it for  
arch/powerpc) be changed to use of_platform_bus_type instead of  
platform_bus_type? In my opinion, cpm_uart driver should take all its  
configuration (uart address base, ints etc) from dts (via the of_platform  
code) without any intervention from board specific code. In any case,  
given the current situation, how can I pass cpm_uart the address/irq of  
the uarts? by hardcoding it in my board specific code? mpc82xx_ads.c  
doesn't seem to have such code, and I was wondering how SCC uarts work in  
this platform? Who initializes them?

thank you

Alex
