Okay, I very quickly looked into the code, what I noticed
- you like extra parens and empty lines in some cases (not big deal)
- some functions perhaps might have been refactored to have common
pieces in error handling, though I didn't read core carefully.

Most important part I have noticed is a GPIO request.
I didn't get why you almost repeat gpiod_get() in case of platform data?
Shouldn't we have GPIO look up table?
Can we use builtin device properties (for GPIO and/or overall)?
