Robin Murphy 9e96f71117 drm/panfrost: Support cache-coherent integrations ... commit 268af50f38 upstream. When the GPU's ACE-Lite interface is fully wired up and capable of snooping CPU caches, it may be described as "dma-coherent" in devicetree, which will already inform the DMA layer not to perform unnecessary cache maintenance. However, we still need to ensure that the GPU uses the appropriate cacheable outer-shareable attributes in order to generate the requisite snoop signals, and that CPU mappings don't create a mismatch by using a non-cacheable type either.
