This could get really verbose in a really big hurry. ?Fortunately the dtb format is sophisticated enough to only store each unique property name once, so the data shouldn't be huge, but it is still going to make for huge source files. ?Can you think of a more concise representation?Yes: no representation at all. The correct place for IOMUX setup being done is *inside the boot firmware as soon as physically possible* and not seconds into boot after U-Boot has made a console, done a boot timeout, loaded scripts, kernels and ramdisks from media and then uncompressed and entered a Linux kernel.
We've had this argument before. There are many use cases where the firmware simply cannot be relied upon to do the right thing. g.
