Subject[PATCH v2 0/2] ARM: sunxi: Enable dwmac-sun8i on more boards
Message-ID<tPN61-1bu-15@gated-at.bofh.it>
Hello

Since the first 3 patch of v1 was applied, it remains this two patchs for
enabling dwmac-sun8i on A83T

Changes since v1:
- Ordered compatible of syscon
- Renamed pins to emac-rgmii-pins

Corentin Labbe (2):
  ARM: sun8i: a83t: Add dt node for the syscon control module
  ARM: sun8i: a83t: add dwmac-sun8i ethernet driver

In reply to#1660042
The dwmac-sun8i is an ethernet MAC hardware that support 10/100/1000 speed.
This patch enable the dwmac-sun8i on the Allwinner a83t SoC Device-tree.
