Subject: [PATCH] mips: dts: ralink: Add support for TP-Link HC220 G5 v1 board.
Date:   Tue,  9 May 2023 21:01:25 +0100
Message-Id: <20230509200125.309026-1-liviu@dudau.co.uk>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

This WiFi AP is based on a MT7621 SoC with 128MiB RAM, 128MiB NAND,
a MT7603 2.4GHz WiFi and a MT7663 5GHz WiFi chips integrated on the board,
connected to the main SoC over PCIe.

The GMAC1 on the SoC is connected to PHY0 on the GSW and can be used to
improve routing bandwidth.

The device uses NMBM over NAND, which is not currently supported in the
mainline, so NAND node is skipped in this revision.
