[ Upstream commit c183c406c4321002fe85b345b51bc1a3a04b6d33 ]
According to the datasheet (Rev. 1.9) the RTL8211F requires at least
72ms "for internal circuits settling time" before accessing the PHY
registers. This fixes an issue seen on ODROID-C2 where the Ethernet
link doesn't come up when using ip link set down/up:

The snps,reset-gpio bindings are deprecated in favour of the generic
"Ethernet PHY reset" bindings.
Replace snps,reset-gpio from the ðmac node with reset-gpios in the
ethernet-phy node. The old snps,reset-active-low property is now encoded
directly as GPIO flag inside the reset-gpios property.
snps,reset-delays-us is converted to reset-assert-us and
reset-deassert-us. reset-assert-us is the second cell from
snps,reset-delays-us while reset-deassert-us was the third cell.
Instead of blindly copying the old values (which seems strange since
they gave the PHY one second to come out of reset) over this also
updates the delays based on the datasheets:
- the Realtek RTL8211F PHY needs a 10ms assert delay (the datasheet
mentions: "For a complete PHY reset, this pin must be asserted low
for at least 10ms") and a 30ms deassert delay (the datasheet
mentions: "Wait for a further 30ms (for internal circuits settling
time) before accessing the PHY register". This applies to the
following boards: GXBB NanoPi K2, GXBB Odroid-C2, GXBB Vega S95
variants, GXBB Wetek variants, GXL P230, GXM Khadas VIM2, GXM Nexbox
A1, GXM Q200, GXM RBox Pro boards.
- the ICPlus IP101GR PHY needs a 10ms assert delay (the datasheet
mentions: "Trst | Reset period | 10ms") and a deassert delay of 10ms
as well (the datasheet mentions: "Tclk_MII_rdy | MII/RMII clock
output ready after reset released | 10ms"). This applies to the GXBB
Nexbox A95X board.
- the Micrel KSZ9031 seems to require a 100us delay but use the same
(seemingly safe) values from RTL8211F due to lack of a board to verify
this. This applies to the GXBB P200 board.
The GXBB P201 board is left out from this conversion because it doesn't
have a dedicated PHY node (because it's not clear which PHY is used on
that board).

Commit 89a5e15bcba8 ("gpio/mmc/of: Respect polarity in the device tree")
changed the behavior of "cd-inverted" to follow the device tree bindings
specification:
According to SDHCI standard, CD lines are specified as "active low".
Using the "cd-inverted" property means that the CD line is "active high".
Fix the SD card description for meson by setting the cd-gpios as
"active low", according to the boards specifications, and dropping the
"cd-inverted" property.

Each CPU can (and does) participate in cooling down the system but the
DT only captures a handful of them, normally CPU0, in the cooling maps.
Things work by chance currently as under normal circumstances its the
first CPU of each cluster which is used by the operating systems to
probe the cooling devices. But as soon as this CPU ordering changes and
any other CPU is used to bring up the cooling device, we will start
seeing failures.
Also the DT is rather incomplete when we list only one CPU in the
cooling maps, as the hardware doesn't have any such limitations.
Update cooling maps to include all devices affected by individual trip
points.

The cooling device properties, like "#cooling-cells" and
"dynamic-power-coefficient", should either be present for all the CPUs
of a cluster or none. If these are present only for a subset of CPUs of
a cluster then things will start falling apart as soon as the CPUs are
brought online in a different order. For example, this will happen
because the operating system looks for such properties in the CPU node
it is trying to bring up, so that it can register a cooling device.
Add such missing properties.
