So what does Ray and Stephen say about this?

Is the hardware unique enough to warrant its own driver?

Or should it utilize/extend one of the existing Broadcom
drivers?

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."


Yours,
Linus Walleij


Thanks,

Ray
