[PATCH v2 01/17] dt-bindings: qcom-bam: Add 'interconnects' & 'interconnect-names' to optional properties

From: Bhupesh Sharma
Date: Wed May 05 2021 - 17:38:10 EST


Add new optional properties - 'interconnects' and
'interconnect-names' to the device-tree binding documentation for
qcom-bam DMA IP.

These properties describe the interconnect path between bam and main
memory and the interconnect type respectively.
