  - interrupts : G2D interrupt number to the CPU.

  - clocks : from common clock binding: handle to G2D clocks.

  - clock-names : from common clock binding: must contain "sclk_fimg2d" and

		  "fimg2d", corresponding to entries in the clocks property.

Example:

	g2d@12800000 {

		compatible = "samsung,s5pv210-g2d";

		reg = <0x12800000 0x1000>;

		interrupts = <0 89 0>;

		clocks = <&clock 177>, <&clock 277>;

		clock-names = "sclk_fimg2d", "fimg2d";

		status = "disabled";

  - interrupts : MFC interrupt number to the CPU.

  - clocks : from common clock binding: handle to mfc clocks.

  - clock-names : from common clock binding: must contain "sclk_mfc" and "mfc",

		  corresponding to entries in the clocks property.

  - samsung,mfc-r : Base address of the first memory bank used by MFC

		    for DMA contiguous memory allocation and its size.

	reg = <0x13400000 0x10000>;

Board specific DT entry:

  - gpio-controller: identifies the node as a gpio controller and pin bank.

  - #gpio-cells: number of cells in GPIO specifier. Since the generic GPIO

    binding is used, the amount of cells must be specified as 2. See generic

    GPIO binding documentation for description of particular cells.

    binding is used, the amount of cells must be specified as 2. See the below

    mentioned gpio binding representation for description of particular cells.

	Eg: <&gpx2 6 0>

	<[phandle of the gpio controller node]

	[pin number within the gpio controller]

	[flags]>

	Values for gpio specifier:

	- Pin number: is a value between 0 to 7.

	- Flags: 0 - Active High

		 1 - Active Low

- Pin mux/config groups as child nodes: The pin mux (selecting pin function

  mode) and pin config (pull up/down, driver strength) settings are represented

		pinctrl = devm_pinctrl_get_select_default(&pdev->dev);

	}

Example 5: A display port client node that supports 'default' pinctrl state

	   and gpio binding.

	display-port-controller {

		/* ... */

		samsung,hpd-gpio = <&gpx2 6 0>;

		pinctrl-names = "default";

		pinctrl-0 = <&dp_hpd>;

	};

Example 6: Request the gpio for display port controller

	static int exynos_dp_probe(struct platform_device *pdev)

	{

		int hpd_gpio, ret;

		struct device *dev = &pdev->dev;

		struct device_node *dp_node = dev->of_node;

		/* ... */

		hpd_gpio = of_get_named_gpio(dp_node, "samsung,hpd-gpio", 0);

		/* ... */

		ret = devm_gpio_request_one(&pdev->dev, hpd_gpio, GPIOF_IN,

					    "hpd_gpio");

		/* ... */

	}

		clocks = <&clock 285>;

		clock-names = "usbhost";

	};

DWC3

Required properties:

 - compatible: should be "samsung,exynos5250-dwusb3" for USB 3.0 DWC3

	       controller.

 - #address-cells, #size-cells : should be '1' if the device has sub-nodes

				 with 'reg' property.

 - ranges: allows valid 1:1 translation between child's address space and

	   parent's address space

 - clocks: Clock IDs array as required by the controller.

 - clock-names: names of clocks correseponding to IDs in the clock property

Sub-nodes:

The dwc3 core should be added as subnode to Exynos dwc3 glue.

- dwc3 :

   The binding details of dwc3 can be found in:

   Documentation/devicetree/bindings/usb/dwc3.txt

Example:

	usb@12000000 {

		compatible = "samsung,exynos5250-dwusb3";

		clocks = <&clock 286>;

		clock-names = "usbdrd30";

		#address-cells = <1>;

		#size-cells = <1>;

		ranges;

		dwc3 {

			compatible = "synopsys,dwc3";

			reg = <0x12000000 0x10000>;

			interrupts = <0 72 0>;

			usb-phy = <&usb2_phy &usb3_phy>;

		};
