Subject: [PATCH v3 3/3] riscv: dts: thead: Add TH1520 ethernet nodes
From: Emil Renner Berthing <emil.renner.berthing@...onical.com>
Add gmac, mdio, and phy nodes to enable the gigabit Ethernet ports on
the BeagleV Ahead and Sipeed Lichee Pi 4a boards.
Signed-off-by: Emil Renner Berthing <emil.renner.berthing@...onical.com>
[drew: change apb registers from syscon to second reg of gmac node,
add phy reset delay properties for beaglev ahead]
