Hi,

The series of patches add AMD Nolan (NL) SoC support for DesignWare USB3
OTG IP with PCI bus glue layer. This controller supported hibernation, LPM
erratum and used the 2.80a IP version and amd own phy. Current
implementation support both simulation and SoC platform. And already tested
with gadget zero and msc tool. It works well on file storage gadget.

These patches are generated on balbi/testing/next

Changes from v3 -> v4
- Add comment on hibernation patch
- Fix typos of commit log and comments
- Remove WARN_ON for temporary solution of FPGA board
- Rename tx deemph to tx de-emphasis
- Add documentation under Documentation/devicetree/bindings/usb/dwc3.txt
- Check FPGA flag on usb3 and usb2 suspend phy quirk
- Refine description of PCI quirk patch
- Remove amd_nl_plat flag at dwc3 structure
- Make HIRD threshold configurable

Changes from v2 -> v3
- Confirmed these quirks will be needed in product level
- Move AMD configuration patch to the last one with all quirk flags
- Make all quirks as 1-bit field instead of single-bits on a 32-bit
variable
- Add all quirks DeviceTree counterparts
- Make LPM erratum configurable
- Add PCI ID into pci_ids.h because it will be used both on PCI and DWC3
device driver.

Changes from v1 -> v2
- Remove dual role function temporarily
- Add pci quirk to avoid to bind with xhci driver
- Distinguish between simulation board and soc
- Break down all the special quirks

Patch 1:
- Enable hibernation

Patch 2:
- Distinguish between simulation board and SoC

Patch 3:
- Initialize platform data at pci glue layer

Patch 4 - 16:
- Break down all the special quirks

Patch 17:
- Add PCI device ID of AMD NL USB3 DRD

Patch 18:
- Prevent xHCI driver from claiming AMD NL USB3 DRD device

Patch 19:
- Add support AMD NL USB3 DRD for dwc3 driver

Patch 20:
- Make HIRD threshold configurable

Patch set already passed all the MSC testing on simulation board with low
clock frequency, so the speed will slower than true SoC. Detailed result
without verbose debug option is below:
