-* MELFAS MIP4 Touchscreen
-
-Required properties:
-- compatible: must be "melfas,mip4_ts"
-- reg: I2C slave address of the chip (0x48 or 0x34)
-- 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@...00000 {
-		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>;
