[PATCH] ARM: dts: BCM5301X: Add DT for Buffalo WZR-1166DHP2

From: SHIMAMOTO Takayoshi
Date: Tue Apr 12 2022 - 11:45:47 EST


Buffalo WZR-1166DHP2 wireless router with

- BCM4708A0
- 256MiB DDR2 SDRAM
- 128MiB NAND flash
- 2T2R 11ac/a/b/g/n Wi-Fi
- 4x 10/100M ethernet switch

The hardware configuration is very similar to the WZR-1750DHP,
except for memory size and number of antennas.
