   4 Subject: [PATCH] ARM: dts: BCM5301X: Add basic DT for Phicomm K3
   5
   6 This router has BCM4709C0, 128MB NAND flash (MX30LF1G18AC-TI),
   7 and 512MB memory, with 3 x LAN and 1 x WAN. WL chips are
   8 BCM4366C0 x 2. The router has a small LCD and 3 capactive keys
   9 driven by a PIC microcontroller, which is in turn wired to
  10 UART1 of main board.
  11
  12 Everything except the LCD works. Hamster has activated LCD through
  13 UART1, but further programming, i.e., a independent package, is
  14 required to make sure its working properly.
  15
  16 Since the firmware of Broadcom 4366c0 has been provided by
  17 openwrt.org, now its wireless is functional but limited. The
  18 "official" firmware cannot work properly in some 5G Hz channel.
