The regulator bindings state that regulator prefixes are allowd to be in upper or lower case. However pmic_bind_children from pmic_uclass uses strncmp to compare DT node name against prefix. This comparison is case sensitive hence the regulator driver prefix case matters.

For the node name e.g.: "prefix[:alpha:]num { ... }": -- the driver prefix should be: "prefix" or "PREFIX" - case insensitive +- the driver prefix should be: "prefix" - case sensitive - the node name's "num" is set as "dev->driver_data" on bind

-Example the prefix "ldo" will pass for: "ldo1", "ldo@1", "LDO1", "LDOREG@1"... +Example the prefix "ldo" will pass for: "ldo1", "ldo@1", "ldoreg@1, ...
