[PATCH v3 1/2] usb:dwc3: Enable support for 64-bit system

From: "Thang Q. Nguyen" Add 64-bit DMA operation support to the USB DWC3 driver. First attempt to set the coherent DMA mask for 64-bit DMA. If that failed, attempt again with 32-bit DMA. Changes from v2: - None. Changes from v1: - Remove WARN_ON if dma_mask is NULL

Re: [PATCH v3 2/2] usb:dwc3: pass arch data to xhci-hcd child

Thanks Grygorii for information. I checked but do not see dma_init_dev_from_parent is used in linux-next repository. Can you give me more information for what branch I can checkout to use it for USB DWC3? Thanks, Thang --

[PATCH v2 2/2] usb:dwc3: pass arch data to xhci-hcd child

The xhci-hcd child node needs to inherit archdata attribute to use dma_ops functions and attributes. This patch enables the USB DWC3 driver to pass archdata attributes to its xhci-hcd child node. Signed-off-by: Thang Q. Nguyen --- Changes from v1: - None drivers/usb/dwc3/host.c | 1
