Looks like this is caused by a buggy patch in the upstream linux kernel.
From my tests, linux kernel versions 6.1.97 and later and 6.6.37 and later are affected.
The broken patch is "pinctrl: rockchip: fix pinmux bits for RK3328 GPIO2-B pins", so any other kernel which lists that patch in the Changelog is liked also affected.
There seems to be a fix at https://patchwork.kernel.org/project/lin...-i@eh5.me/, but this fix is not released yet.
