Same for other cases.
The "multipleOf: 100" doesn't seen appropriate to me when the choice is
350, 450, 550, 650. Those are not multiples of 100. It's more of a step
size. I didn't find a general property for step size. Listing them as
"enum" would be another possibility, I guess, but not an elegant one.
Especially for property "richtek,const-microvolt" there are 30
possibilities.
Ahh, right. You can use enum here and min/max for other cases, where
multipleOf cannot be used.

Here are two different step sizes. The first few are 50 mA steps (150,
200, 250, 300 mA) and then it changes to 100 mA steps (300, 400, 500,
600 mA). How to deal with that? Again I guess "enum" would be a
possibility, but again not a nice one.
enum
Thanks for the reply. Looking through the properties, I get the
following result.
