Subject: [PATCH 1/2] arm64: dts: rockchip: Add phy-supply to gmac0 on NanoPi R5S
Date: Sat, 3 May 2025 17:22:18 +0200 [thread overview]
Message-ID: <20250503152917.138648-2-didi.debian@cknow.org> (raw)
In-Reply-To: <20250503152917.138648-1-didi.debian@cknow.org>
According to paragraph "7.16. Power" of the RTL8211F-CG datasheet, gmac0
needs to have a 3.3V power supply.
On page 22 of the NanoPi R5S version 2204, that is identified as
VCC_GEPHY_3V3 which is connected to the VCC_3V3 power source.
This fixes the following warning:
rk_gmac-dwmac fe2a0000.ethernet: supply phy not found, using dummy regulator
