What you describe in this subnode is the pinctrl state, that's why we
decided to make it '-state$' instead of '-pins$'.

So please revert this back to what you had in v4 and fix the example
instead.

I think I might have mislead you on this one. The valid gpios are gpio0
through gpio107 according to the driver. So the last 9 should be a 7.

The 109 in gpio-ranges is correct though, as that's number of gpios in
{gpio0..gpio107 + ufs_reset}.

Thanks,
Bjorn
