[V2,0/6] Add XHCI, EHCI and OHCI support for Broadcom STB SoS's

Message

V2 - Based on feedback, the functionality for XHCI and OHCI was
     moved from Broadcom platform drivers into the standard XHCI
     and OHCI platform drivers. The EHCI functionality still uses
     a Broadcom EHCI driver because of the workarounds needed for
     bugs in the EHCI controller.

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 (6):
  dt-bindings: Add Broadcom STB OHCI, EHCI and XHCI binding document
  usb: core: Add ability to skip phy exit on suspend and init on resume
  usb: xhci: xhci-plat: Add support for Broadcom STB SoC's
  usb: ohci-platform: 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
