[U-Boot] [RFT PATCH v2 0/2] sunxi: Enable EMAC on A83T boards using Realtek RTL8211E PHY

[Chen-Yu Tsai]

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

[U-Boot] [RFT PATCH v2 1/2] sunxi: Enable EMAC on the Cubietruck Plus

[Chen-Yu Tsai]

From: Chen-Yu Tsai <wens@csie.org>

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.

[U-Boot] [RFT PATCH v2 2/2] sunxi: Enable EMAC on the Bananapi M3

[Chen-Yu Tsai]

From: Chen-Yu Tsai <wens@csie.org>

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.
