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 regula= tor Signed-off-by: Diederik de Haas --- arch/arm64/boot/dts/rockchip/rk3568-nanopi-r5s.dts | 1 + 1 file changed, 1 insertion(+) diff --git a/arch/arm64/boot/dts/rockchip/rk3568-nanopi-r5s.dts b/arch/arm6= 4/boot/dts/rockchip/rk3568-nanopi-r5s.dts index e50f1585244a..805cb23493e8 100644 --- a/arch/arm64/boot/dts/rockchip/rk3568-nanopi-r5s.dts +++ b/arch/arm64/boot/dts/rockchip/rk3568-nanopi-r5s.dts @@ -61,6 +61,7 @@ &gmac0 { clock_in_out =3D "output"; phy-handle =3D <&rgmii_phy0>; phy-mode =3D "rgmii"; + phy-supply =3D <&vcc_3v3>; pinctrl-names =3D "default"; pinctrl-0 =3D <&gmac0_miim &gmac0_tx_bus2 --=20 2.49.0
