Georgi Djakov	9a34e7ad2e	dt-bindings: interconnect: Document the support of optional path tag ... Let's document that we now support specifying path tag information in the arg cells of the 'interconnects' DT property. This information would be populated when the xlate_extended() callback is used. Specifying the tag in DT will allow the interconnect framework to do the aggregation based on the tag automatically. The users can still use the icc_set_tag() API if/when needed.

Maxime Ripard	c43a446940	dt-bindings: interconnect: Add a dma interconnect name ... The current DT bindings assume that the DMA will be performed by the devices through their parent DT node, and rely on that assumption for the address translation using dma-ranges. However, some SoCs have devices that will perform DMA through another bus, with separate address translation rules. We therefore need to express that relationship, through the special interconnect name "dma-mem".

Georgi Djakov	06b3773b50	dt-bindings: Introduce interconnect binding ... This binding is intended to represent the relations between interconnect controllers (providers) and consumer device nodes. It will allow creating links between consumers and interconnect paths (exposed by interconnect providers).
