Subject: [PATCH] net: stmmac: dwmac-sun8i: Add a shutdown callback
The Ethernet MAC and PHY are usually major consumers of power on boards
which may not be able to fully power off (those with no PMIC). Powering
down the MAC and internal PHY saves power while these boards are "off".

Subject: [PATCH] arm64: dts: allwinner: orange-pi-3: Enable ethernet
Orange Pi 3 has two regulators that power the Realtek RTL8211E
PHY. According to the datasheet, both regulators need to be enabled
at the same time, or that "phy-io" should be enabled slightly earlier
than "phy" regulator.
RTL8211E/RTL8211EG datasheet says:
Note 4: 2.5V (or 1.8/1.5V) RGMII power should be risen simultaneously
or slightly earlier than 3.3V power. Rising 2.5V (or 1.8/1.5V) power
later than 3.3V power may lead to errors.
The driver ensures the regulator enable ordering. The timing is set
in DT via startup-delay-us.
We also need to wait at least 30ms after power-up/reset, before
accessing the PHY registers.
All values of RX/TX delay were tested exhaustively and a middle one
of the range of working values was chosen.

Subject: [PATCH] net: stmmac: sun8i: Use devm_regulator_get for PHY regulator
Use devm_regulator_get instead of devm_regulator_get_optional and rely
on dummy supply. This avoids NULL checks before regulator_enable/disable
calls.
This path also improves error reporting, because we now report both
use of dummy supply and error during registration with more detail,
instead of generic info level message "No regulator found" that
was reported previously on errors and lack of regulator property in DT.
Finally, we'll be adding further optional regulators, and the overall
code will be simpler.
