Any thoughts how we should handle the serial mux mode (SPMOD in SPSWC) in the NPCM? It seems we need to able to switch between modes runtime (as these are customer configurable options that can change at anytime). 

We use almost all the modes in some fashion...  

Could this be a handled like the 8250_aspeed_vuart.c? Maybe another simple sysfs driver? Thoughts?
