-* Freescale i.MX6UL Touch Controller
-
-Required properties:
-- compatible: must be "fsl,imx6ul-tsc".
-- reg: this touch controller address and the ADC2 address.
-- interrupts: the interrupt of this touch controller and ADC2.
-- clocks: the root clock of touch controller and ADC2.
-- clock-names; must be "tsc" and "adc".
-- xnur-gpio: the X- gpio this controller connect to.
-  This xnur-gpio returns to low once the finger leave the touch screen (The
-  last touch event the touch controller capture).
-
-Optional properties:
-- measure-delay-time: the value of measure delay time.
-  Before X-axis or Y-axis measurement, the screen need some time before
-  even potential distribution ready.
-  This value depends on the touch screen.
-- pre-charge-time: the touch screen need some time to precharge.
-  This value depends on the touch screen.
-- touchscreen-average-samples: Number of data samples which are averaged for
-  each read. Valid values are 1, 4, 8, 16 and 32.
-
-Example:
-	tsc: tsc@2040000 {
-		compatible = "fsl,imx6ul-tsc";
-		reg = <0x02040000 0x4000>, <0x0219c000 0x4000>;
