Re: [PATCH] dt-bindings: pwm: Convert NXP PCA9685 PWM controller to DT schema

Hello Krzysztof + all,

Dean is a middle name I use in place of my surname, Clifton, so both
names are mine. I should have used the same one in both places; that
mismatch is my mistake.

The goal was to bring this binding up to par with the rest of the PWM
bindings, so that device trees and overlays using the PCA9685 can be
validated with dtbs_check. It's a common chip in beginner robotics
projects, and the schema means the beginners who run dtbs_check can be
sure their DTS has no mismatches.

For reference, I put together a template for DT schemas:

and a requirements document which could be a starter guide for someone putting
together such a schema:

Look out for a v2 with zero hallucination sashiko flags (My middle name is Dean).

Jeremy

I think we are done on these hallucinations.

There is little point for beginner contributors to send us DT binding
conversions generated by LLM.

Best regards,
