[PATCH v3 0/6] inherit dma configuration from parent dev

[Sriram Dash]

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
