From 33237616771bfc29a97f17e74efe3799bb790343 Mon Sep 17 00:00:00 2001 From: Russell King Date: Sun, 22 Jan 2012 20:05:24 +0000 Subject: MFD: ucb1x00-core: add wakeup support Add genirq wakeup support for the ucb1x00 device. This allows an attached gpio_keys driver to wakeup the system. Touchscreen is also possible. When there are no wakeup sources, ask the platform to assert the reset signal to avoid any unexpected behaviour; this also puts the reset signal at the right level when power is removed from the device.
