Providing a > list_voltage() would be nice and make things more robust. Still, setting selector in this case does nothing, as it is immediately overwritten by the regulator core by -1. This looks like a perfectly acceptable way to implement a regulator, as everything checks for the presence of list_voltage anyway. If you really insist, I could probably make something that does a list_voltage and shows min and max voltages for the regulator, but I don't know about the usefulness of that. -Tero -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
