1 * Freescale i.MX6UL Touch Controller
4 - compatible: must be "fsl,imx6ul-tsc".
5 - reg: this touch controller address and the ADC2 address.
6 - interrupts: the interrupt of this touch controller and ADC2.
7 - clocks: the root clock of touch controller and ADC2.
8 - clock-names; must be "tsc" and "adc".
9 - xnur-gpio: the X- gpio this controller connect to.
10 This xnur-gpio returns to low once the finger leave the touch screen (The
11 last touch event the touch controller capture).
14 - measure-delay-time: the value of measure delay time.
15 Before X-axis or Y-axis measurement, the screen need some time before
16 even potential distribution ready.
17 This value depends on the touch screen.
18 - pre-charge-time: the touch screen need some time to precharge.
19 This value depends on the touch screen.
