Subject: [PATCH] ARM: BCM5301X: Specify USB 3.0 PHY in DT
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Driver for Northstar USB 3.0 PHY has been recently added under the name
phy-bcm-ns-usb3. Add binding for it into the DT files.
The only slightly tricky part is BCM47094 which uses different PHY
version and requires different compatible value.
