It looks like all kernel modules that used gpio lines with RPi4 now do not work anymore on RPi5 because of the use on RPi5 of a different chip for gpios than with RPi4. Coherently, when I tried to port to RPi5 the gpib_bitbang driver of the linux-gpib package, I failed. What are now the rules to access and use gpio lines from a kernel module? I mean, gpio_request_one() and all functions of that family are still usable someway with RPi5? Am I missing something important?
Many thanks for your attention.
