Device Tree • Re: Bookworm - Device tree overlays not loading

Which I would have done earlier if I'd received a notification. phpBB can be useless at times.

I seem to recall PhilE saying that there was a recent change that removed the need for pinctrl and GPIO assignments.

I'm not sure what you are referring to. I investigated the use of strict mode in the pinmux driver, but it hasn't been enabled because it would require many overlays to be changed.

Loading from config.txt with noints override logs

Code:

[    6.503778] mcp230xx 1-0020: prop pinctrl-0 index 0 invalid phandle

That's hardly surprising, because the pinctrl-0 property is left with a reference to a non-existing node, and hence an invalid phandle. But you're the first to mention noints, so I'm not sure of the relevance.

@dloranger Are you sure that the driver isn't failing to load because of a missing dependency? What does "cat /sys/kernel/debug/devices_deferred" report? Does lsmod show the module as having been loaded?
