[U-Boot] [RFT PATCH v2 0/2] sunxi: Enable EMAC on A83T boards using Realtek RTL8211E PHY
From: Chen-Yu Tsai wens@csie.org
Hi everyone,
This series enables EMAC (Ethernet controller) on two A83T boards, the Cubietruck Plus and Bananapi M3.
This series is now based on sunxi/next, which has patches that convert sun8i-emac to use the common CLK and DM_RESET framework.
The two patches enable the sun8i-emac and Realtek PHY driver in their respective defconfigs. The device trees already have the EMAC enabled. For the Bananapi M3, the regulator providing the I/O voltages is raised to 3.3V.
As I currently do not have access to my boards, testing by others is requested.
Regards ChenYu
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

The Cubietruck Plus has an RTL8211E PHY connected to the EMAC using RGMII. The PHY is powered by DLDO4 @ 3.3V, while the I/O pins are powered by DLDO3 @ 2.5V.
This patch enables the EMAC and Realtek PHY drivers in the defconfig. The device tree file already has the EMAC enabled.

The Bananapi M3 has an RTL8211E PHY connected to the EMAC using RGMII. 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.
