-Subject: [PATCH] drm/vc4: Adopt the dma configuration from the HVS or
- V3D component
-
-vc4_drv isn't necessarily under the /soc node in DT as it is a
-virtual device, but it is the one that does the allocations.
-The DMA addresses are consumed by primarily the HVS or V3D, and
-those require VideoCore cache alias address mapping, and so will be
-under /soc.
-
-During probe find the a suitable device node for HVS or V3D,
-and adopt the DMA configuration of that node.
-
