These patches add support for XHCI compliant Host controller found
on Fujitsu Socs, and are based on http://lwn.net/Articles/629162/
The first patch is to add Fujitsu glue layer of Synopsis DesignWare USB3 driver
and last four patch is about quirk implementation of errata in Synopsis
DesignWare USB3 IP.

Patch 1 introduces a quirk with device disconnection management necessary
Synopsys Designware USB3 IP with versions < 3.00a and hardware configuration
DWC_USB3_SUSPEND_ON_DISCONNECT_EN=1. It solves a problem where without the
quirk, that host controller will die after a usb device is disconnected from
port of root hub.

Patch 2 is to set Synopsis quirk in xhci platform driver based on xhci platform
data.

Patch 3 is to add a revison number 2.90a and 3.00a of Synopsis DesignWare USB3
IP core driver.

Patch 4 introduces using a quirk based on a errata of Synopsis
DesignWare USB3 IP which is versions < 3.00a and has hardware configuration
DWC_USB3_SUSPEND_ON_DISCONNECT_EN=1, which cannot be read from software. As a
result this quirk has to be enabled via platform data or device tree.

Patch 5 introduces Fujitsu Specific Glue layer in Synopsis DesignWare USB3 IP
driver. 

Successfully tested on Fujitsu mb86s7x board.

Changes since v2 (RFC):
[https://lkml.org/lkml/2014/12/15/929]
 - based on Felipe's comment, re-order patches to avoid breaking bisectability,
 - based on Felipe's comment, add comment to structure's member, and sort it
   alphabetically,
 - based on Felipe's comment, add another v2.90 revision number in dwc3 IP.

Changes since v1 (RFC):
[https://lkml.org/lkml/2014/12/15/929]
 - based on Arnd's comment, remove entire unnecessary Fujitsu EHCI/OHCI glue,
 - based on Felipe's comment, fix mis-using of runtime-pm API and setting dma
   mask, remove unnecessary comment, and refactor suspend/resume handler in
   Fujitsu Specific Glue layer in dwc3,
 - based on Felipe's comment, add more commit log and comments in Synopsis
   quirk implementation, and separate it into four patches.

Sneeker Yeh (5):
  xhci: add a quirk for device disconnection errata for Synopsis
    Designware USB3     core
  xhci: Platform: Set Synopsis device disconnection quirk based on
    platform data
  usb: dwc3: add revision number DWC3_REVISION_290A and
    DWC3_REVISION_300A
  usb: dwc3: Add quirk for Synopsis device disconnection errata
  usb: dwc3: add Fujitsu Specific Glue layer
