+Subject: ARM: dts: Use cpsw ethernet driver for some am335x devices
+
+The new cpsw-switch driver requires a vid for every port which is
+reserved for internal usage (defaulting to 1 and 2). As a result, some
+network configurations are impossible, such as a bridge with
+default_pvid of 1 (even if it is not vlan aware).
+
+As a simple workaround, the ti,dual-emac-pvid property could be changed
+to another value, but that would just shift the problem. Instead, switch
+some devices back to the older cpsw ethernet driver.
+
+(This patch is not suitable for upstreaming, it just makes the affected
+devices in OpenWrt usable again with the default network config.)
