+* MELFAS MIP4 Touchscreen
+
+Required properties:
+- compatible: must be "melfas,mip4_ts"
+- reg: I2C slave address of the chip (0x48 or 0x34)
+- interrupt-parent: interrupt controller to which the chip is connected
+- interrupts: interrupt to which the chip is connected
+
+Optional properties:
+- ce-gpios: GPIO connected to the CE (chip enable) pin of the chip
+
+Example:
+        i2c@00000000 {
+                touchscreen: melfas_mip4@48 {
+                        compatible = "melfas,mip4_ts";
+                        reg = <0x48>;
+                        interrupt-parent = <&gpio>;
+                        interrupts = <0 IRQ_TYPE_EDGE_FALLING>;
+                        ce-gpios = <&gpio 0 GPIO_ACTIVE_HIGH>;
+                };
