+* EETI eGalax Multiple Touch Controller
+Required properties:
+- compatible: must be "eeti,egalax_ts"
+- 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@04 {
+                compatible = "eeti,egalax_ts";
+                reg = <0x04>;

+                wakeup-gpios = <&gpio1 9 0>;
