Due to a change in kernel 6.2, the GPIO numbers on certain architectures (including arm64) have changed. This script will update any defined GPIO switches to the new numbering. See https://lists.openwrt.org/pipermail/openwrt-devel/2024-March/042448.html for more information. In the future, the GPIO switch mechanism will likely be replaced with something using libgpiod.
