So if they depend on a certain type of SoC, which they should, then we can get these initialized from that SoC's dts/dtsi file instead of a common file.. And so that would resolve the issue you just reported. Now I haven't proposed in the patch that we will change these voltage levels at all.. This is regulator specific code and would come into play only when regulators are registered for cpu.. Otherwise we will just play with frequency.. Passing OPP instead of just list of frequencies is the generic way this is done now a days.. -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
