Subject: [PATCH 1/4] dt-bindings: dma: qcom,bam-dma: Add 'interconnects' and
 'interconnect-names'

From: Abel Vesa <abel.vesa@...aro.org>

Add 'interconnects' and 'interconnect-names' as optional properties
to the device-tree binding documentation for BAM DMA IP.

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