+Subject: [PATCH] ARM: dts: BCM5301X: Linksys EA9500 add fixed partitions
+
+This router has dual paritions to store trx firmware image and
+dual partitions for nvram. The second one in each of these cases acts
+as a backup store.
+
+When tested with OpenWrt, the default partition parser causes two issues:
+
+1. It labels both nvram partitions as nvram. In factory, second one is
+labeled devinfo.
+2. It parses second trx image and tries to create second 'linux' partition
+and fails with - cannot create duplicate 'linux' partition
+
+The following patch works around both of these issues.

+Subject: [PATCH] ARM: dts: BCM5301X: Use corretc pinctrl compatible for 4709x
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+BCM47094 version of pinmux uses different compatible and supports MDIO
+pinmux pins. Hence, use the correct compatible string and defines the
+MDIO pins group.

+
+Now that we have a pin controller, use that instead of manuplating the
+mdio/mdc pins directly. i.e. we no longer require the mdio-mii-mux
