   4 Subject: [PATCH] ARM: dts: BCM5301X: Add DT for WZR-1166DHP,DHP2
   5
   6 Buffalo WZR-1166DHP/WZR-1166DHP2  wireless router with
   7
   8     - BCM4708A0
   9     - 128MiB NAND flash
  10     - 2T2R 11ac/a/b/g/n Wi-Fi
  11     - 4x 10/100/1000M ethernet switch
  12     - 1x USB 3.0 port
  13
  14   WZR-1166DHP and WZR-1166DHP2 have different memory capacity.
  15
  16   WZR-1166DHP
  17     - 512 MiB DDR2 SDRAM
  18
  19   WZR-1166DHP2
  20     - 256 MiB DDR2 SDRAM
  21
  22   These hardware components are very similar to the WZR-1750DHP
  23    except for the number of antennas.
