+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>;
+ };
+};
