Subject[PATCH v6 7/8] dt-bindings: Introduce interconnect consumers bindings
Date
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.

+= interconnect consumers =
+
+The interconnect consumers are device nodes which consume the interconnect
+path(s) provided by the interconnect provider. 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";
+ };
