From 60a3437dc9a61c7f4b199c2bac3dcc7b611b1178 Mon Sep 17 00:00:00 2001 From: Tarun Kanti DebBarma Date: Thu, 29 Sep 2011 04:47:25 +0530 Subject: gpio/omap: handle save/restore context in GPIO driver Modify omap_gpio_prepare_for_idle() & omap_gpio_resume_after_idle() functions to handle save context & restore context respectively in the OMAP GPIO driver itself instead of calling these functions from pm specific files. For this, in gpio_prepare_for_idle(), call *_get_context_loss_count() and in gpio_resume_after_idle() call it again. If the count is different, do restore context.
