Subject: arm: sun8i: sunxi-h3-h5: Add dt node for the syscon control module
|
||||
|
||||
This patch add the dt node for the syscon register present on the
|
||||
Allwinner H3/H5
|
||||
|
||||
Only two register are present in this syscon and the only one useful is
|
||||
the one dedicated to EMAC clock..

Subject: arm: sun8i: sunxi-h3-h5: add dwmac-sun8i ethernet driver
|
||||
|
||||
The dwmac-sun8i is an ethernet MAC hardware that support 10/100/1000
|
||||
speed.
|
||||
|
||||
This patch enable the dwmac-sun8i on Allwinner H3/H5 SoC Device-tree.
|
||||
SoC H3/H5 have an internal PHY, so optionals syscon and ephy are set.
