If I understood you comments an example OFDT node for IPMI could look  
like the following:

name = "ipmi"
device_type = "ipmi"
compatible = "ipmi-kcs"

reg = XXXXXXX8 00000008
reg-spacing = 4
reg-size    = 1
reg-shift   = 0

In this example the Data_In / Data_out sitting at address XXXXXXX8  
and Status / Command is sitting at XXXXXXXC. Does this layout look  
good to everybody?

Is the "8" of the reg property correct?

I'm still worried what happens when we have a BT or SMIC interface an  
the registers sitting at XXXXXXX4, XXXXXXX6, XXXXXXXA. In this case  
the reg-spacing property can't be used anymore. Can this happen in  
reality?
