-Bindings for EETI touchscreen controller
-
-Required properties:
-- compatible:	should be "eeti,exc3000-i2c"
-- reg:		I2C address of the chip. Should be set to <0xa>
-- interrupts:	interrupt to which the chip is connected
-
-Optional properties:
-- attn-gpios:	A handle to a GPIO to check whether interrupt is still
-		latched. This is necessary for platforms that lack
-		support for level-triggered IRQs.
-
-The following optional properties described in touchscreen.txt are
-also supported:
-
-- touchscreen-inverted-x
-- touchscreen-inverted-y
-- touchscreen-swapped-x-y
-
-Example:
-
-i2c-master {
-	touchscreen@a {
-		compatible = "eeti,exc3000-i2c";
-		reg = <0xa>;
-		interrupt-parent = <&gpio>;
-		interrupts = <123 IRQ_TYPE_EDGE_RISING>;
-		attn-gpios = <&gpio 123 GPIO_ACTIVE_HIGH>;
-	};
