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:

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

I'm now getting this error:

Traceback (most recent call last):

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?
