Subject: [PATCH 0/3] inherit dma configuration from parent dev

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.

Sriram Dash (3):
  usb: dwc3: host: inherit dma configuration from parent dev
  usb: dwc3: host: Do not use dma_set_coherent_mask
  usb: dwc3: host: Do not use dma_coerce_mask_and_coherent
