It is possible that PCI device supports 64-bit DMA addressing, and thus
it's driver sets device's dma_mask to DMA_BIT_MASK(64), however PCI host

bridge has limitations on inbound transactions addressing. Example of
such setup is NVME

   Isn't it called NVMe?

SSD device connected to RCAR PCIe controller.

   R=Car.

    Sorry, R-Car. :-)
