+Subject: [PATCH] ARM: dts: BCM5301X: Add DT for Phicomm K3
+
+This router has BCM4709C0, 128MB NAND flash (MX30LF1G18AC-TI),
+and 512MB memory, with 3 x LAN and 1 x WAN. WL chips are
+BCM4366C0 x 2. The router has a small LCD and 3 capactive keys
+driven by a PIC microcontroller, which is in turn wired to
+UART1 of main board.
+
+Everything except the LCD and wireless works.
+
+The founder of the patch is: Tian Hao <haotia@gmail.com>
+
+Signed-off-by: Hao Dong <halbertdong@gmail.com>
