Never seen this before.  Looks like more of a commit log entry than
something that should live in a source file header.

No need to mention "platform driver" here. Most drivers are.

You only use this variable one.  Just switch it out for the macro.

This is fragile.  Just define a GPIO_CONTROLLER_COUNT or similar.

What's happening here?  Are you manually pulling resources out of the
resource structure and linking them to the device cells?

Why?

Why res++?

Are you sure this does what you think it does?


I think you will keep changing *.name, and the only one you will
see/use is the last one.

Have you tested this?

No, this is a failure.  You need to 'error' out and return ret.

You've just passed the child device a NULL pointer.

Why are you returning 0 even during failure?

What does this move have to do with this patch?

I think it should be separate and be paired with a reason for the
change.
