+- pinctrl-2: pinctrl node for gpios functioning as FET gate drivers
+- vf50-ts-min-pressure: pressure level at which to stop measuring X/Y values

+Required properties:
+- compatible: must be "fsl,imx6ul-tsc".

+- 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.

+- measure-delay-time: the value of measure delay time.

+  This value depends on the touch screen.
+- pre-charge-time: the touch screen need some time to precharge.

+* Atmel SAMA5D4 Watchdog Timer (WDT) Controller
+
+Required properties:
+- compatible: "atmel,sama5d4-wdt"
+- reg: base physical address and length of memory mapped region.
+
+Optional properties:
+- timeout-sec: watchdog timeout value (in seconds).
+- interrupts: interrupt number to the CPU.
+- atmel,watchdog-type: should be "hardware" or "software".
+	"hardware": enable watchdog fault reset. A watchdog fault triggers
+		    watchdog reset.
+	"software": enable watchdog fault interrupt. A watchdog fault asserts
+		    watchdog interrupt.
+- atmel,idle-halt: present if you want to stop the watchdog when the CPU is
+		   in idle state.
+	CAUTION: This property should be used with care, it actually makes the
+	watchdog not counting when the CPU is in idle state, therefore the
+	watchdog reset time depends on mean CPU usage and will not reset at all
+	if the CPU stop working while it is in idle state, which is probably
+	not what you want.
+- atmel,dbg-halt: present if you want to stop the watchdog when the CPU is
+		  in debug state.
+
+Example:
+	watchdog@fc068640 {
+		compatible = "atmel,sama5d4-wdt";
+		reg = <0xfc068640 0x10>;
+		interrupts = <4 IRQ_TYPE_LEVEL_HIGH 5>;
