Support for Raspberry Pi 5

[nashafa]

I'm having trouble getting this library to work on a Raspberry Pi 5. My understanding is that GPIO support has a few breaking changes on the Pi 5; this may or may not be related to my issue.

I've installed lua-periphery with luarocks and am using Lua 5.1. I'm on Bookworm and Linux kernel 6.6.

When using the sysfs GPIO mode I get the following error:

Opening GPIO: writing 'export': Invalid argument [errno 22]

When attempting to use the character device GPIO mode (to target /dev/gpiochip4), I get the following error.

c-periphery library built without character device GPIO support.

Let me know if there's any further information I can provide or any additional tests to run. Thanks for the help!
