The egalax_ts driver needs to get the gpio number of the irq pin, and use this gpio to wake up the controller. So add a note for this change.

Since we define this in the binding anyway, can we have an corresponding .of_match_table in the driver? Regards, Shawn
+- reg: i2c slave address
+- interrupt-parent: the phandle for the interrupt controller
+- interrupts: touch controller interrupt
+- wakeup-gpios: the gpio pin to be used for waking up the controller
+ as well as uased as irq pin

+Example:

+ egalax_ts at 04 {
+ compatible = "eeti,egalax_ts";
+ reg = <0x04>;
+ interrupt-parent = <&gpio1>;
+ interrupts = <9 2>;
+ wakeup-gpios = <&gpio1 9 0>;
