From e949f93c591352f0376fdd192b4060a38c102ba5 Mon Sep 17 00:00:00 2001 From: Paul Parsons Date: Wed, 2 May 2012 16:49:24 +0100 Subject: [PATCH] ARM: pxa: hx4700: Enable ASIC3 GPIO as a wakeup source This patch enables the ASIC3 GPIO (12) as a wakeup source: 1. Set the WAKEUP_ON_EDGE_RISE MFP config bits for GPIO12 in hx4700_pin_config[]. 2. Call gpio_set_wake() for GPIO12. With GPIO12 thus enabled, the mfd/asic3 driver can enable its own GPIOs as wakeup sources by implementing a irq_set_wake() handler.
