[PATCH v2 1/4] dt-bindings: Add Broadcom STB USB support

From: Al Cooper <alcooperx@gmail.com>
Date: 2020-03-27 20:47:40
Also in: linux-usb, lkml
Subsystem: broadcom brcmstb usb ehci driver, open firmware and flattened device tree bindings, the rest, usb subsystem · Maintainers: Justin Chen, Al Cooper, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds, Greg Kroah-Hartman

Add DT bindings for Broadcom STB USB EHCI and XHCI drivers.

NOTE: The OHCI driver is not included because it uses the generic
      platform driver.
