So it is single function LED driver. That does not mean it can not
share bindings with the rest. Where the bindings live is not imporant.

What you forgot to tell us in the changelog:

> +Optional child properties:

> +				the a higher brightness level.
> +				Range from 2048 us - 117.44 s

The other binding uses "ramp-up-msec". Tell us why you are changing this, or
better don't change things needlessly.

We don't want to be using "runtime-ramp-up-msec" for one device and
"ramp-up-msec" for the other.

I'm not sure what other changes you did, and changelog does not tell
me.

NAK. You can use existing binding.
