I know I'm late, and this patch has already been applied, but shouldn't
we use of_get_child_by_name instead of of_find_node_by_name.
This might lead to wrong regulators node parsing if other regulators are
defined in the DT after the axp20x node, because, AFAIK, this function
searches for DT nodes defined after the specified np node, but not
necessarely children of the np node.

Best Regards,

Boris
