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.
