+Subject: [PATCH] ARM: dts: BCM5301X: Describe Northstar pins mux controller
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This describes hardware & will allow referencing pin functions. The
+first usage is UART1 which allows supporting devices using it.
