    Subject[PATCH v3 0/6] inherit dma configuration from parent dev
    Date
    For xhci-hcd platform device, all the DMA parameters are not
    configured properly, notably dma ops for dwc3 devices.

    The idea here is that you pass in the parent of_node along
    with the child device pointer, so it would behave exactly
    like the parent already does. The difference is that it also
    handles all the other attributes besides the mask.

    Arnd Bergmann (6):
    usb: separate out sysdev pointer from usb_bus
    usb: chipidea: use bus->sysdev for DMA configuration
    usb: ehci: fsl: use bus->sysdev for DMA configuration
    usb: xhci: use bus->sysdev for DMA configuration
    usb: dwc3: use bus->sysdev for DMA configuration
    usb: dwc3: Do not set dma coherent mask
