Subject: [PATCH v3 0/4] Add XHCI, EHCI and OHCI support for Broadcom STB SoS's

v3 - Addressed all of Andy Shevchenko's review comments for
     ehci-brcm.c.
   - Fixed the brcm,bcm7445-ehci.yaml dt-bindings document,
     dt_binding_check now passes.
   - Added the XHCI functionality to xhci-plat.c instead of creating
     new brcmstb files, as suggested by Mathias Nyman.

v2 - Addressed Andy Shevchenko's review comments.
   - Fixed dt_binding_check error pointed out by Rob Herring.
   - Removed pr_info message in ehci_brcm_init as suggested by
     Greg Kroah-Hartman.

This adds support for the XHCI, EHCI and OHCI host controllers found
in Broadcom STB SoC's. These drivers depend on getting access to the
new Broadcom STB USB PHY driver through a device-tree phandle and
will fail if the driver is not available.

Al Cooper (4):
  dt-bindings: Add Broadcom STB USB support
  usb: xhci: xhci-plat: Add support for Broadcom STB SoC's
  usb: ehci: Add new EHCI driver for Broadcom STB SoC's
  usb: host: Add ability to build new Broadcom STB USB drivers
