From mboxrd@z Thu Jan 1 00:00:00 1970 From: Rhyland Klein Subject: [PATCH V2 0/3] Add DT Binding for Power-Supply power-supplies property Date: Mon, 1 Apr 2013 17:45:52 -0400 Message-ID: <1364852755-17425-1-git-send-email-rklein@nvidia.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: Sender: linux-tegra-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: Anton Vorontsov , Grant Likely Cc: David Woodhouse , linux-kernel-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, devicetree-discuss-uLR06cmDAlY/bJ5BZ2RsiQ@public.gmane.org, linux-tegra-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, Rhyland Klein List-Id: devicetree@vger.kernel.org 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.
