Hello,

The purpose of this patch set is to switch from driver xhci-fsl to
dwc3-generic for DWC3 IP on Layerscape platforms. Whith this change, now
user can enable USB device mode by merely updating property 'dr_mode'
accordingly.

I also port some DWC3's errata workaorunds from driver
xhci-fsl (by referring to Linux kernel mainline version implemenattion).

Besides that, I fixed a PHY init problem which observed on Lyerscape
platforms (such as LS1088ardb).

Regards,
Ran

Change in v2:
 - Remove [2/7] usb: dwc3: add disable receiver detection in P3 quirk, because
   I found it causes Linux kenrel fail to detect USB device, need further check.

Ran Wang (6):
  usb: dwc3: Add frame length adjustment quirk
  usb: dwc3: Enable undefined length INCR burst type
  usb: dwc3-generic: fix dwc3_setup_phy() return -ENOTSUPP causing init
    failure
  usb: dwc3-generic: Add support for the layerscape
  configs: ls1088a: add usb mass storage (device mode) support
  arm: dts: ls1088a: change dwc3 compatible to match dwc3-generic driver
