I can not tell. At the moment i am in a Siemens internal review where i
see code that is not even close to being ready for upstream. Somewhat
open-coded again from what it looks like.

And i do not have the machine the code is for.

Let me say "it is complicated" but some point in time a device with
LEDs attached to PINCTRL_ELKHARTLAKE will be proposed. Likely by me,
when i hopefully have such a device on my desk.
