-Device tree bindings for Atmel capacitive touch device, typically
-an Atmel touch sensor connected to AtmegaXX MCU running firmware
-based on Qtouch library.
-
-The node for this device must be a child of a I2C controller node, as the
-device communicates via I2C.
-
-Required properties:
-
-	compatible:	Must be "atmel,captouch".
-	reg:		The I2C slave address of the device.
-	interrupts:	Property describing the interrupt line the device
-			is connected to. The device only has one interrupt
-			source.
-	linux,keycodes:	Specifies an array of numeric keycode values to
-			be used for reporting button presses. The array can
-			contain up to 8 entries.
-
-Optional properties:
-
-	autorepeat:	Enables the Linux input system's autorepeat
-			feature on the input device.
-
-Example:
-
-	atmel-captouch@51 {

-* 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>;
-		interrupts = <GIC_SPI 3 IRQ_TYPE_LEVEL_HIGH>,
-			     <GIC_SPI 101 IRQ_TYPE_LEVEL_HIGH>;
-		clocks = <&clks IMX6UL_CLK_IPG>,
-			 <&clks IMX6UL_CLK_ADC2>;
-		clock-names = "tsc", "adc";
-		pinctrl-names = "default";
-		pinctrl-0 = <&pinctrl_tsc>;
-		xnur-gpio = <&gpio1 3 GPIO_ACTIVE_LOW>;
-		measure-delay-time = <0xfff>;
-		pre-charge-time = <0xffff>;
-		touchscreen-average-samples = <32>;
