V3: Although have got Ack-by from driver author in the V2, i have to send V3 since the driver is changed due to the change of a property name in the dts. As Shawn.guo suggested, i renamed property "irq-gpio" to "wakeup-gpios". The reason is that, firstly the idiom of gpio naming in DT is *-gpios, even though most of time, it could be just one gpio, secondly as the pin is accessed as a gpio only in egalax_wake_up_device for waking up the device. This time i send the patches both to linux-input and linux-arm, 0001 and 0002 belongs to linux-input, while the 0003 belongs to linux-arm. V2: Add return value checking for waking up the controller in the probe function. V1: eeti touch screen controller is an external chip for most platforms, it connect to CPU via i2c bus, and it has a irq request pin need to be connected to a gpio of the CPU, this irq request pin also act as a wake up signal for touch screen controller, we need to get this gpio number and operate it to wake up the controller, the old way to get gpio is irq_to_gpio(), this API is dying and most platforms don't support it, we change it to a more generic way to use devcietree.
