Should we mark it for stable? Nothing is using it, I found out because I've a group of students from my local university working on a gsl1680 driver, and one of the a23 q8 tablets I've used ldoio1 to power the touchscreen controller. But that is not upstream yet, so nothing uses it, and thus I see no reason for a Cc: stable.
