What is next to the device tree? AFAIK, there is no other standard data
structure that could take place of the par_io nodes in the DTS.
I agree with your points, Segher, but replacing the par_io node with a bunch
of par_io_config_pin() calls in the kernel is not really an improvement, I
think. Until we migrate the QE pin configuration code to U-boot, I suggest
that we keep the device tree structure as-is and continue to use it for new
code. That way, it will all stay in one place.
