Adreno bus monitor device



kgsl-busmon is a psedo device that represents a devfreq bus bandwidth

governor. If this device is present then two different governors are used

for  GPU DCVS and bus DCVS.



Required properties:

- compatible:	Must be "qcom,kgsl-busmon"

- label:	Device name used for sysfs entry.



Example:



	qcom,kgsl-busmon {

		compatible = "qcom,kgsl-busmon";

		label = "kgsl-busmon";

	};
