after some testing, the issues with bcmpins 4 and 15 were indeed that they were pull-up, this means that the issue lies with the device tree overlay not working as intended. two properties have been added to hopefully make this overlay load as intended. the compatible field has been uncommented as the driver is stable enough to be loaded automatically.
