The PHY is powered by DCDC1 through SW @ 3.3V. The board is designed to use 3.3V with RGMII, instead of the standard reduced voltage of 2.5V we see everywhere. DLDO3, which provides the I/O voltages, is raised to match. This patch enables the EMAC and Realtek PHY drivers in the defconfig. The device tree file already has the EMAC enabled. Signed-off-by: Chen-Yu Tsai --- Changes in v3: - Rebased on sunxi/master Changes in v2: - Dropped clk/reset related changes in favor of DM CLK / RESET support - Raised DLDO3 for RGMII I/O on Bananapi M3 to 3.3V per design configs/Sinovoip_BPI_M3_defconfig | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/configs/Sinovoip_BPI_M3_defconfig b/configs/Sinovoip_BPI_M3_defconfig index 79743a9c9a51..b9ab00cb8a29 100644 --- a/configs/Sinovoip_BPI_M3_defconfig +++ b/configs/Sinovoip_BPI_M3_defconfig @@ -21,8 +21,10 @@ CONFIG_CONSOLE_MUX=y # CONFIG_SPL_DOS_PARTITION is not set # CONFIG_SPL_EFI_PARTITION is not set CONFIG_DEFAULT_DEVICE_TREE="sun8i-a83t-bananapi-m3" +CONFIG_PHY_REALTEK=y +CONFIG_SUN8I_EMAC=y CONFIG_AXP_DCDC5_VOLT=1200 -CONFIG_AXP_DLDO3_VOLT=2500 +CONFIG_AXP_DLDO3_VOLT=3300 CONFIG_AXP_SW_ON=y CONFIG_USB_EHCI_HCD=y CONFIG_USB_OHCI_HCD=y
