Description
RPi.GPIO /sys interface was removed from the Raspberry Pi Linux kernel. python3-lgpio is a compatibility package that allows us to continue to use RPi.GPIO, however, its days are numbered as we should be moving to the new kernel/character devices to access GPIO pins, which is python3-gpiod. The lgpio shim layer introduces its own problems.
Possible to migrate from RPi.GPIO to gpiod ?
adafruit_blinka/microcontroller/bcm283x/pin.py for example...
thanks!

Research direction
Start with adafruit_blinka/microcontroller/bcm283x/pin.py, the example named in the issue, and trace how the RGB display drivers reach GPIO access. Compare the current RPi.GPIO path with the python3-gpiod character-device approach; done means the GPIO access path is migrated without relying on the lgpio shim.
