Date: Sat, 12 Apr 2008 13:47:45 +0200 From: Philipp Zabel <philipp.zabel@...il.com> To: linux-kernel@...r.kernel.org Cc: Anton Vorontsov <cbou@...l.ru> Subject: [PATCH] pda_power: add init and exit function callbacks This adds init/exit function callbacks to pda_power, to provide a place where the platform code can request/free GPIOs that it wants to use in the is_ac_online, is_usb_online and set_charge functions.
