Nicolas Saenz Julienne has contributed a kernel driver for the Raspberry POE hat fan which is available in 5.13 and newer kernels. I have 4 RPI4 devices in my home lab running Fedora 34, all powered by the POE Hat. I was able to get the Hat fan working well with Fedora 34 and the 5.13 kernel. I outline the steps I followed at https://raspberrypi.stackexchange.com/questions/118863/how-can-i-enable-the-fan-on-the-official-poe-hat-under-fedora for anyone who is interested. Please note that this process modifies the upstream firmware device tree file for the RPi4, and that this device tree file is not the same one Raspberry provides (even though they share the same name). thanks Brad _______________________________________________ arm mailing list -- arm@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to arm-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/arm@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
