+* 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>;
+ };
+ };
