Hello Bartosz,

No, this is literally how you do it. If you enable HAVE_SHARED_GPIOs and
DEBUG_GPIO, you should see it being picked up in the kernel log.
Ah, HAVE_SHARED_GPIOS is what I did not have enabled. Is there any
reason why this is not enabled by default ?


It will be. I'm doing it gradually. It's enabled for Qualcomm platforms by
default and - by extension - in arm64 defconfig. I plan to enable it for other
platforms and architectures too, I just don't want to rush it. Enabling it for
arm64 defconfig had caused quite a lot of regressions a few months ago so I
prefer to be careful.

What platform are you running this on?
NXP i.MX8M Nano (arm64)
