This series defines a common way for devicetree initialized power_supplies to define their relationships between chargers and supplicants. This series adds a supplied_from array to complement the supplied_to array and to allow supplies to define the list of supplies which supply them. Then once this property is supported, we can use a new property for devicetree to define the relationships between nodes, and read in this property to generate the supplied_from list. With this logic in place, all drivers need to do to add support for this mechanism, is to store their device tree node in the power_supply struct. They should also handle EPROBE_DEFER properly. Changes since: v2: - Changed __power_supply_is_supplied_by to a boolean function and corrected return paths around it - took loop invariant tests out of loops - Fixed multiline comment style - fixed up return paths around power_supplies_check_supplies RFC v2: - Changed to official Patch set rather than RFC - defined supplied_from char ** array rather than complicated struct device_node related array RFC v1: - Inverted the logic so that supplies (batteries) contain a list of the supplies (chargers) which supply them.
