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. -- Timur Tabi Linux Kernel Developer @ Freescale
