Subject: [PATCH v3 6/6] regulator: dt-bindings: rtq2208: Add property to get ldo of RTQ2208 is adjustable or not
Since there is no way to check is ldo is adjustable or not.
As discussing in v2 series, 'richtek,fixed-microvolt' is added for that.
user is supposed to know whether vout of ldo is adjustable.
