Subject: [PATCH] ARM: dts: BCM5301X: Add basic DT for Phicomm K3
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This router has BCM4709C0 SoC, 128 MiB NAND flash (MX30LF1G18AC-TI),
512 MiB memory and 3 x LAN and 1 x WAN ports. WiFi 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.
