====================
net-next: stmmac: add dwmac-sun8i ethernet driver
This patch series add the driver for dwmac-sun8i which handle the Ethernet MAC
present on Allwinner H3/H5/A83T/A64 SoCs.
This driver is the continuation of the sun8i-emac driver.
During the development, it appeared that in fact the hardware was a modified
version of some dwmac.
So the driver is now written as a glue driver for stmmac.
It supports 10/100/1000 Mbit/s speed with half/full duplex.
It can use an internal PHY (MII 10/100) or an external PHY
via RGMII/RMII.
This patch series enable the driver only for the H3/A64/H5 SoC since A83T
doesn't have the necessary clocks present in mainline.
The driver have been tested on the following boards:
- H3 Orange PI PC, BananaPI-M2+
- A64 Pine64, BananaPi-M64
- A83T BananaPI-M3
The first two patchs are some mandatory changes for letting dwmac-sun8i be used.
The following three patchs add the driver and its documentation.
The remaining are DT patch enabling it.
Regards
Corentin Labbe

As the firmware flash process takes about 20 seconds and ethtool takes the
rtnl lock during the flash_device callback, release the rtnl lock at the
beginning of the flash process and take it again before leaving the
callback. This way, the rtnl is not held during the process. To make sure
the device does not get deleted during the flash process, take a reference
