The bus scaling driver also provides the ability to configure

bus performance parameters across the entire chip-set.

Various clients use MSM scaling APIs to request bandwidth

between multiple master-slave pairs. The bus driver then finds

the optimal path between the master and the slave, and aggregates

the bandwidth and clock requests for all master-slave pairs on

that path, and programs hardware accordingly.

The device-tree data required for bus-scaling can be embedded within

the clients' device nodes. The clients can register with the bus driver

using the following properties:

- qcom,msm-bus,name:		String representing the client-name

- qcom,msm-bus,num-cases:	Total number of usecases

- qcom,msm-bus,active-only:	Boolean context flag for requests in active or

				dual (active & sleep) contex

- qcom,msm-bus,num-paths:	Total number of master-slave pairs

- qcom,msm-bus,vectors-KBps:	Arrays of unsigned integers representing:

				master-id, slave-id, arbitrated bandwidth

				in KBps, instantaneous bandwidth in KBps

Example:

	qcom,msm-bus,name = "client-name";

	qcom,msm-bus,num-cases = <3>;

	qcom,msm-bus,active-only;

	qcom,msm-bus,num-paths = <2>;

	qcom,msm-bus,vectors =

			<22 512 0 0>, <26 512 0 0>,

			<22 512 320000 3200000>, <26 512 3200000 3200000>,

			<22 512 160000 1600000>, <26 512 1600000 1600000>;

MSM Bus Devices for adhoc bus topologies

Buses are the interconnects between various devices. The devices are

connected in different topologies. The bus scaling driver accepts

bandwidth requests from clients and ensures that the bandwidth requests

can be met between the source and destination for that client.

In order to accept and honor bandwidth requests the bus scaling driver

needs to know about the bus topology.

This device tree binding represents the bus devices in the SOC, their

connections to other bus devices and the resources associated with each

node. The bus scaling driver uses this device tree to setup the bus

topology in order to apply client bandwidth requests.

				criterion are satisfied. Possible values are

				THROTTLE_ON/THROTTLE_OFF

- qcom,dest-node:		An array of phandles representing the nodes to

				which the QoS mode is to be applied.

The optional properties for the rule node are:

- qcom,dest-bw:			The destination bandwidth value in Kbytes/s to

				be used toward the QoS mode for the destination

				node.

Example:

	static-rules {

		compatible = "qcom,msm-bus-static-bw-rules";

		#address-cells = <1>;

		#size-cells = <0>;

		rule@0 {

			qcom,src-nodes = <&mas_apss>;

			qcom,src-field = <FLD_IB>;

			qcom,src-op = <OP_LE>;

			qcom,thresh = <1599078>;

			qcom,mode = <THROTTLE_ON>;

			qcom,dest-node = <&mas_apss>;

			qcom,dest-bw = <1599078>;

		};

		rule@1 {

			qcom,src-nodes = <&mas_apss>;

			qcom,src-field = <FLD_IB>;

			qcom,src-op = <OP_GT>;

			qcom,thresh = <1599078>;

			qcom,mode = <THROTTLE_OFF>;

			qcom,dest-node = <&mas_apss>;

		};
