'Easiest' method for getting the SDIO interface on GPIO22-27 working is documented along with the other device tree overlay stuff in /boot/firmware/overlays/README - https://github.com/raspberrypi/linux/bl ... ADME#L4054
Add this line to /boot/firmware/config.txt:The various options (1-bit vs. 4-bit, clock speed, etc) are documented in the README. Adding the poll_once=off makes the OS poll the slot every second to detect card presence. Otherwise it only looks once, at boot time.
Sorry, but no idea if that will work on a Pi5 as the GPIO are via RP1!!!
