Mark (in his reply) has a point. If these are internally connect, we should just remove them from the bindings, and associate them in the driver. I'm looking into this. In the mean time, could you drop this one?

The DC1SW and DC5LDO regulators in the AXP221 are internally chained to DCDC1 and DCDC5, hence the names. The original bindings used the parent regulator names for the supply regulator property. This causes some confusion when we actually use it in the dts: axp221 { /* self supplying? */ dcdc1-supply = <&dcdc1>; dcdc5-supply = <&dcdc5>; dcdc1: dcdc1 { ... }; dcdc5: dcdc5 { ... }; }; Change them to the downstream regulator names, or "dc1sw" and "dc5ldo" respectively.
