Subject: [PATCH V4 1/5] dt-bindings: Add Broadcom STB USB support
Date: Fri,  9 Nov 2018 09:01:56 -0500	[thread overview]
Message-ID: <1541772120-40394-2-git-send-email-alcooperx@gmail.com> (raw)
In-Reply-To: <1541772120-40394-1-git-send-email-alcooperx@gmail.com>

Add DT bindings for Broadcom STB USB EHCI and XHCI drivers.
Add "phy-supplies-usb-clock" property description to usb-hcd.txt

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