Subject: [PATCH] arm64: dts: renesas: beacon: Fix Ethernet PHY mode
Git-commit: 59a8bda062f8646d99ff8c4956adf37dee1cb75e
Patch-mainline: v5.16-rc1
References: stable-5.14.19
[ Upstream commit 59a8bda062f8646d99ff8c4956adf37dee1cb75e ]
While networking works fine in RGMII mode when using the Linux generic
PHY driver, it fails when using the Atheros PHY driver.
Fix this by correcting the Ethernet PHY mode to RGMII-RXID, which works
fine with both drivers.
