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.Thank you
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.
