Hi,
Hi I am trying to add a device which is '/dev/gpiomem' in
Fedora IOT 37 aarch64. But I can only see '/dev/gpiochip0' and
'/dev/gpiochip1' how can I add gpiomem device because the software I am installing
is using this device in their code.
The /dev/gpiomem interface is a Raspberry Pi downstream driver
(drivers/char/broadcom/bcm2835-gpiomem.c) that isn't upstream so it's
not something we will support in Fedora. The only interface for
interfacing with GPIOs in Fedora is the upstream non deprecated
character interface (/dev/gpiochipX) and the assoicated libgpiod
library and associated language bindings.
