+* MELFAS MMS114 touchscreen controller
+
+Required properties:
+- compatible: must be "melfas,mms114"
+- reg: I2C address of the chip
+- interrupts: interrupt to which the chip is connected
+- x-size: horizontal resolution of touchscreen
+- y-size: vertical resolution of touchscreen
+
+Optional properties:
+- contact-threshold:
+- moving-threshold:
+- x-invert: invert X axis
+- y-invert: invert Y axis
+
+Example:
+
+ i2c@00000000 {
+ /* ... */
+
+ touchscreen@48 {
+ compatible = "melfas,mms114";
+ reg = <0x48>;
+ interrupts = <39 0>;
+ x-size = <720>;
+ y-size = <1280>;
+ contact-threshold = <10>;
+ moving-threshold = <10>;
+ x-invert;
+ y-invert;
+ };
