Hey There,
So, I am trying to declare data in DTS format to handle the PCA9685 on board the Servo Cape from the BeagleY-AI in userspace.
Is the BeagleY-AI image(s) already hardcoded for i2c to perform a specific way without intervention of any kind?
Can intervention be performed to handle i2c from userspace on the BeagleY-AI image with kernel 6.1.x and what exact dtb is needed?
Also, would something like this DTS be in a working order for the BeagleY-AI?

I keep reading and cyclic endurance has beat me once again. If you know more than me, jump on in. I will keep learning.
