[PATCH v4 0/3] Input: egalax_ts: parse devicetree to get gpio

[Hui Wang <jason77.wang@gmail.com>]

V4:

add of_match_table in the driver, and change egalax_ts gpio irq type value from
2 to 8 (falling edge to low level) in the dts.

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.
