-* Elan eKTF2127 I2C touchscreen controller
-
-Required properties:
- - compatible		  : "elan,ektf2127" or "elan,ektf2132"
- - reg			  : I2C slave address of the chip (0x40)
- - interrupts		  : interrupt specification for the ektf2127 interrupt
- - power-gpios		  : GPIO specification for the pin connected to the
-			    ektf2127's wake input. This needs to be driven high
-			    to take ektf2127 out of its low power state
-
-For additional optional properties see: touchscreen.txt
-
-Example:
-
-i2c@...00000 {
-	ektf2127: touchscreen@15 {
-		compatible = "elan,ektf2127";
-		reg = <0x15>;
-		interrupt-parent = <&pio>;
-		interrupts = <6 11 IRQ_TYPE_EDGE_FALLING>
-		power-gpios = <&pio 1 3 GPIO_ACTIVE_HIGH>;
-		touchscreen-inverted-x;
-		touchscreen-swapped-x-y;
-	};
