[PATCH v7 7/8] dt-bindings: Introduce interconnect consumers bindings

[Georgi Djakov]

Add documentation for the interconnect consumer bindings, that will allow
to link a device node (consumer) to its interconnect controller hardware.

Tha aim is to enable drivers to request a framework API to configure an
interconnect path by providing their struct device pointer and a name.

+The interconnect consumers are device nodes which dynamically express their
+bandwidth requirements along interconnect paths they are connected to. There
+can be multiple interconnect providers on a SoC and the consumer may consume
+multiple paths from different providers depending on use case and the
+components it has to interact with.
+
+Required properties:
+interconnects : Pairs of phandles and interconnect provider specifier to denote
+	        the edge source and destination ports of the interconnect path.
+
+Optional properties:
+interconnect-names : List of interconnect path name strings sorted in the same
+		     order as the interconnects property. Consumers drivers will use
+		     interconnect-names to match interconnect paths with interconnect
+		     specifiers.
+
+Example:
+
+	sdhci@7864000 {
+		...
+		interconnects = <&pnoc MASTER_SDCC_1 &bimc SLAVE_EBI_CH0>;
+		interconnect-names = "ddr";
+	};
