[PATCH v7 8/9] arm64: dts: qcom: shikra: Add OPE node

[Loic Poulain]

From: Nihal Kumar Gupta <nihal.gupta@xxxxxxxxxxxxxxxx>

Add the Offline Processing Engine (OPE) device tree node for Shikra.
The node describes the six register regions (cdm, top, qos, pipeline,
bus_read, bus_write), clocks, interrupt, interconnects, IOMMU mappings,
and OPP table.

OPE is a memory-to-memory block with no board-level dependencies, so
the node is left enabled for all Shikra boards.
