What is a DCP platform?

cannot discover display resources through direct register access. The DRM driver therefore needs device-tree descriptions of the Qualcomm transport wrapper, display topology, IOMMU contexts, and panel connections.

Add bindings for the Qualcomm DCP transport wrapper and VirtIO display subsystem. Document the IPCC power-notify resources, transport and framebuffer IOMMU contexts, firmware-visible IOVA range, INTF graph, and DSI panel connections. The wrapper creates a standard VirtIO-MMIO child after the IPCC power-notify sequence has completed.

It's still DT for real hardware, so I wonder why no SoC specific compatibles were used.
