Qualcomm adreno/snapdragon GPU

Required properties:
- compatible: "qcom,adreno-XYZ.W", "qcom,adreno"
    for example: "qcom,adreno-306.0", "qcom,adreno"
  Note that you need to list the less specific "qcom,adreno" (since this
  is what the device is matched on), in addition to the more specific
  with the chip-id.
- reg: Physical base address and length of the controller's registers.
- interrupts: The interrupt signal from the gpu.
- clocks: device clocks
  See ../clocks/clock-bindings.txt for details.
- clock-names: the following clocks are required:
  * "core"
  * "iface"
  * "mem_iface"

Example:

/ {
	...

	gpu: qcom,kgsl-3d0@4300000 {
		compatible = "qcom,adreno-320.2", "qcom,adreno";
		reg = <0x04300000 0x20000>;
		reg-names = "kgsl_3d0_reg_memory";
		interrupts = <GIC_SPI 80 0>;
		interrupt-names = "kgsl_3d0_irq";
		clock-names =
		    "core",
		    "iface",
		    "mem_iface";
		clocks =
		    <&mmcc GFX3D_CLK>,
		    <&mmcc GFX3D_AHB_CLK>,
		    <&mmcc MMSS_IMEM_AHB_CLK>;
	};
};
