Patch is fine but looks like 
Mux framework seems to be not efficient.

"There is one GLOBAL table for all omap devices." 
How maintainable is that? 
Also care has to be taken to match the enum position with mux.c array location. This is error prone.

Mux tables should be per device basis.
Any thoughts.
