+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+It was tested by LEDE users, all we need is to adjust clock frequency.
+While we're at it create a separated DTS include file to share code with
+other BCM4709 devices easier.

+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.
