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