The UP board <https://up-board.org/> is the computer board for
Professional Makers and Industrial Applications. We want to upstream
the UP board 40-pin GP-bus Kernel driver for giving the users better
experience on the software release. (not just download from UP board
github)

These patches are generated from the Linux kernel mainline tag v6.0.

This is the PATCH V5 and fixed kernel test robot compiler warning and
addressed Lee Jones review comments.
