Message

v10 - Fix incorrect error return in ehci-brcmstb.c pointed out by
      Alan Stern.

v9 - Fix minor typos in patch description for ehci driver.
   - In ehci-brcm.c, use ehci_err() instead of dev_err().
   - In ehci-brcm.c, handle zero returned from platform_get_irq()
     by returning -EINVAL for 0 or actual return value for < 0.

v8 - The previous v7 had the wrong version of ehci-brcm.c. This time
     really, really add the changes Greg requested.

v7 - Cleanup ehci-brcm.c as requested by Greg Kroah-Hartman.
   - Split out Makefile re-order change into a separate commit.

v6 - Remove "contains:" from compatible section of
     brcm,bcm7445-ehci.yaml as requested by Rob Herring.

v5 - Use devm_platform_get_and_ioremap_resource() in ehci-brcm.c
     as requested by Andy Shevchenko.
   - Add pm_runtime_set_active() to ehci_resume() in ehci-brcm.c
     as requested by Alan Stern.

v4 - A few more fixes to the brcm,bcm7445-ehci.yaml dt-bindings
     document requested by Rob Herring.
   - Fixed ordering issue in MAINTAINERS as requested by
     Andy Shevchenko.

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 (5):
  usb: xhci: Change the XHCI link order in the Makefile
  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
