Subject: [PATCH 0/3] Add support for Fujitsu USB host controller

These patches add support for EHCI and XHCI compliant Host controller found
on Fujitsu Socs, and are based on
http://www.spinics.net/lists/arm-kernel/msg385573.html

First patch is EHCI platform glue driver. Patch 2 introduces Fujitsu
Specific Glue layer in Synopsis DesignWare USB3 IP driver. Patch 3
introduces a quirk with device disconnection management necessary for IPs
using the Synopsys Designware dwc3 core. It solves a problem where without
the quirk, that host controller will die after a usb device is disconnected
from port of root hub, which happened in Synopsis core with Fujitsu
config-free usb phy integrated.

Successfully tested on Fujitsu mb86s7x board.

Sneeker Yeh (3):
  usb: host: f_usb20ho: add support for Fujitsu ehci/ohci USB 2.0 host
    controller
  usb: dwc3: add Fujitsu Specific Glue layer
  usb: dwc3: add a quirk for device disconnection issue in Synopsis
    dwc3 core
