MSM BIMC bandwidth monitor device



bimc-bwmon is a device that represents the MSM BIMC bandwidth monitors that

can be used to measure the bandwidth of read/write traffic from the BIMC

master ports. For example, the CPU subsystem sits on one BIMC master port.



Required properties:

- compatible:		Must be "qcom,bimc-bwmon"

- reg:			Pairs of physical base addresses and region sizes of

			memory mapped registers.

- reg-names:		Names of the bases for the above registers. Expected

			bases are: "base", "global_base"

- interrupts:		Lists the threshold IRQ.

- qcom,mport:		The hardware master port that this device can monitor

- qcom,target-dev:	The DT device that corresponds to this master port



Example:

	qcom,cpu-bwmon {

		compatible = "qcom,bimc-bwmon";

		reg = <0xfc388000 0x300>, <0xfc381000 0x200>;

		reg-names = "base", "global_base";

		interrupts = <0 183 1>;

		qcom,mport = <0>;

		qcom,target-dev = <&cpubw>;

	};
