[U-Boot] [RESEND PATCH 0/4] sunxi: Enable EMAC on A83T boards using Realtek RTL8211E PHY
From: Chen-Yu Tsai wens@csie.org
(Resending from correct email address and with proper cover letter subject.)
Hi everyone,
This series enables EMAC (Ethernet controller) on two A83T boards, the Cubietruck Plus and Bananapi M3.
A couple of changes are required to the clock definitions to make the compiler happy, as it hasn't been coverted to use the common CLK and DM_RESET framework. These changes are not used in the A83T code path.
The other two patches enable the sun8i-emac and Realtek PHY driver in their respective defconfigs. The device trees already have the EMAC enabled.
Since these are compile time issues, all patches should go through the same tree.
Regards ChenYu

The A83T has its own clock header file and clock control module structure, unlike H3/A64/R40 which share a common one. As such some of the SoC specific fields or macros are undefined when building U-boot for A83T.
Add dummy entries to the clock control module structure to make the compiler happy. The code path using these fields is unused for A83T in the driver.

Define the AHB_RESET_OFFSET_EPHY macro if it isn't already defined to make the compiler happy. The code path including this macro is unused in the driver for A83T.

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.
This patch enables the EMAC and Realtek PHY drivers in the defconfig. The device tree file already has the EMAC enabled.
