[U-Boot] [PATCH v3 00/10] USB: XHCI: Add xHCI host controller stack driver

[Vivek Gautam]

Based on 'master' branch of u-boot-usb tree.

The series also includes patches to support xHCI on exynos5250,
including required driver, device tree changes.

Changes since V2:
 - Added patch to move 'bmRequestType' (Table 9-2, Ch9) definitions
   from EHCI header file to usb_defs.h so that XHCI can also use it:
   usb: Move 'bmRequestType' USB device request macros from EHCI header
 - Added patches to rework the Vbus GPIO setup for ehci and xhci in
   exynos SoCs:
   exynos: usb: Switch USB VBUS GPIOs to be device tree configured
   exynos: dts: Add USB VBUS GPIOs to the device tree
 - Added the top commit history for drivers/usb/host/xhci* of Linux kernel
   version 3.4 from where the xHCI code was initially imported.
 - Replaced GPL license with new SPDX license GPL-2.0+.
 - Moved this "asm/io.h" file inclusion to xhci.h
 - Reworked 'return -1' globally to return meaningful error numbers.
 - Added required comment in common/usb.c for not calling first get_descriptor
   request for XHCI.
