Hello!
I use Fedora 25 on my Raspberry Pi 3. I would like to use DHT22 driver from Adafruit but there is no /dev/gpiomem device in Fedora 25. It seems that bcm2835-gpiomem kernel module is missing.
Many drivers and libraries use this device for GPIO access. Is there a package with bcm2835-gpiomem kernel mdule?
This is 3rdparty driver not present in mainline Linux kernel source. Fedora is shipping mainline kernel.
Consider asking raspberry foundation developers to get it upstreamed.
In meantime use GPIO like it is done on several other mainline supported devices.
