+Subject: [PATCH] ARM: dts: BCM5301X: Add DT for ASUS RT-AC3100
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+ASUS RT-AC3100 is ASUS RT-AC88U without the external switch. Move the
+shared bindings to bcm47094-asus-rt-ac3100.dtsi.
+
+Remove the fixed-link node on port@7 as commit ba4aebce23b2 ("ARM: dts:
+BCM5301X: Describe switch ports in the main DTS") states it's not
+necessary.
+
+Replace the copyright notice with an author notice.
+
+Rename the model name from Asus to ASUS on bcm47094-asus-rt-ac88u.dts.
