[PATCH v5 2/8] dt-bindings: Introduce interconnect provider bindings

[Georgi Djakov]

This binding is intended to represent the interconnect hardware present
in some of the modern SoCs. Currently it consists only of a binding for
the interconnect hardware devices (provider).

+Interconnect Provider Device Tree Bindings
+=========================================
+
+The purpose of this document is to define a common set of generic interconnect
+providers/consumers properties.
+
+
+= interconnect providers =
+
+The interconnect provider binding is intended to represent the interconnect
+controllers in the system. Each provider registers a set of interconnect
+nodes, which expose the interconnect related capabilities of the interconnect
+to consumer drivers. These capabilities can be throughput, latency, priority
+etc. The consumer drivers set constraints on interconnect path (or endpoints)
+depending on the use case. Interconnect providers can also be interconnect
+consumers, such as in the case where two network-on-chip fabrics interface
+directly
+
+Required properties:
+- compatible : contains the interconnect provider compatible string
+- #interconnect-cells : number of cells in a interconnect specifier needed to
+			encode the interconnect node id
+
+Example:
+
+		snoc: snoc@580000 {
+			compatible = "qcom,msm8916-snoc";
+			#interconnect-cells = <1>;
+			reg = <0x580000 0x14000>;
+			clock-names = "bus_clk", "bus_a_clk";
+			clocks = <&rpmcc RPM_SMD_SNOC_CLK>,
+				 <&rpmcc RPM_SMD_SNOC_A_CLK>;
+		};
