+Qualcomm adreno/snapdragon GPU
+
+Required properties:
+- compatible: "qcom,adreno-3xx"
+- 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_clk"
+  * "iface_clk"
+  * "mem_iface_clk"
+- qcom,chipid: gpu chip-id.  Note this may become optional for future
+  devices if we can reliably read the chipid from hw
+- qcom,gpu-pwrlevels: list of operating points
+  - compatible: "qcom,gpu-pwrlevels"
+  - for each qcom,gpu-pwrlevel:
+    - qcom,gpu-freq: requested gpu clock speed
+    - NOTE: downstream android driver defines additional parameters to
+      configure memory bandwidth scaling per OPP.
+
+Example:
+
+/ {

+
+	gpu: qcom,kgsl-3d0@4300000 {
