Currently, the IOMUX configurations in Cygnus, NSP, and NS2 are 
completely different and require a separate driver to each of these 
SoCs. We now realize the shortcomings and have been communicating with 
our ASIC team. We'd like to fix this for the next-gen of our SoC. We are 
driving towards using a register layout that will allow us to use just 
"pinctrl-single" and "pinconf-single."
