Subject: [PATCH] usb: dwc3: core: clarify usb-phy array binding
Date: Fri,  9 Aug 2013 10:40:32 -0500	[thread overview]
Message-ID: <1376062832-23288-1-git-send-email-galak@codeaurora.org> (raw)

The binding spec wasn't clear that the order of the phandles in the
usb-phy array has meaning.  Clarify this point in the binding that
it should be <USB2-HS-PHY, USB3-SS-PHY>.
