Please add support for the OrangePiCM4

[nerdathome]

I have 2 versions of the OrangePi CM4 found here: http://www.orangepi.org/html/hardWare/computerAndMicrocontrollers/service-and-support/Orange-Pi-CM4-1.html running on their image of Debian. 1 has 2GB RAM w/ 32GB EMMC and the other has 8GB RAM w/ 64GB EMMC. The below is from the 8GB model:

Carrier board is the 2.5" version of this from GeekWorm: https://geekworm.com/collections/nas-storage/products/naspi-cm4-m2.

I've followed https://learn.adafruit.com/adding-a-single-board-computer-to-platformdetect-for-blinka?view=all and now have detect.py working:

$ python3 ~/repos/Adafruit_Python_PlatformDetect/bin/detect.py Board Detection Test

Check that the Chip and Board IDs match your board and that this it is correctly detecting whether or not it is a Linux board.

Chip id: RK3566 Board id: ORANGE_PI_CM4

I'm now getting this error:

Traceback (most recent call last): File "~/repos/geekworm/oled/monitor.py", line 4, in import digitalio

File "/usr/local/lib/python3.11/dist-packages/digitalio.py", line 97, in from adafruit_blinka.microcontroller.rockchip.rk3566.pin import Pin

File "/usr/local/lib/python3.11/dist-packages/adafruit_blinka/microcontroller/rockchip/rk3566/pin.py", line 182, in if board in ("ODROID_M1S"): ^^^^^^^^^^^^^^^^^^^^^^^ TypeError: 'in ' requires string as left operand, not NoneType

Does this mean the scripts think the only board with an RK3566 is an ODROID_M1s? And since an Orange Pi CM4 has a different pin out the pin.py script fails? And if so, do I just need to add an "else if" exit for the OrangePi_CM4 & copy the RaspberryPi CM4 gpio pin out code block?
