[ Upstream commit 3d07c3b3a8 ]
According to the datasheet (Rev. 1.9) the RTL8211F requires at least
72ms "for internal circuits settling time" before accessing the PHY
registers. On similar boards with the same PHY this fixes an issue where
Ethernet link would not come up when using ip link set down/up.

Enable DVFS for the U200, SEI520 and X96-Max Amlogic G12A based board
by setting the clock, OPP and supply for each CPU cores.
The CPU cluster power supply can achieve 0.73V to 1.01V using a PWM
output clocked at 800KHz with an inverse duty-cycle.
DVFS has been tested by running the arm64 cpuburn at [1] and cycling
between all the possible cpufreq translations and checking the final
frequency using the clock-measurer, script at [2].

X96 Max has the PHY reset and interrupt lines are identical to the
Odroid-N2:
- GPIOZ_14 is the interrupt on X96 Max
- GPIOZ_15 is the reset line on X96 Max
Add GPIOZ_14 as PHY interrupt line on the X96 Max so we don't have to
poll for the PHY status.

The Odroid-N2 schematics show that the following pins are used for the
reset and interrupt lines:
- GPIOZ_14 is the PHY interrupt line
- GPIOZ_15 is the PHY reset line
The GPIOZ_14 and GPIOZ_15 pins are special. The datasheet describes that
they are "3.3V input tolerant open drain (OD) output pins". This means
the GPIO controller can drive the output LOW to reset the PHY. To
release the reset it can only switch the pin to input mode. The output
cannot be driven HIGH for these pins.
This requires configuring the reset line as GPIO_OPEN_DRAIN because
otherwise the PHY will be stuck in "reset" state (because driving the
pin HIGH seems to result in the same signal as driving it LOW).
The reset line works together with a pull-up resistor (R143 in the
Odroid-N2 schematics). The SoC can drive GPIOZ_14 LOW to assert the PHY
reset. However, since the SoC can't drive the pin HIGH (to release the
reset) we switch the mode to INPUT and let the pull-up resistor take
care of driving the reset line HIGH.
Switch to GPIOZ_15 for the PHY reset line instead of using GPIOZ_14
(which actually is the interrupt line).
Move from the "snps" specific resets to the MDIO framework's
reset-gpios because only the latter honors the GPIO flags.
Use the GPIO flags (GPIO_ACTIVE_LOW | GPIO_OPEN_DRAIN) to match with
the pull-up resistor because this will:
- drive the output LOW to reset the PHY (= active low)
- switch the pin to INPUT mode so the pull-up will take the PHY out of
reset

There is no branding for the manufacturer anywhere on the product, so it
took some digging[2] to find the manufacturer. But since there's
nothing about the maker on the product I've left it out of the DT name
because 1) nobody will know that name and 2) keeps the DT filename
shorter.
