Due to the special handling of window 13 on Armada 375 and Armada 38x
(similar to Armada XP), the MBus hardware block is *not* compatible
with the one used on Armada 370. Using the Armada 370 compatible
string on Armada 375 and 38x will lead to a non-working device if
window 13 ends up being used.

In order to update MAC address entries in the ethernet nodes in Device Tree
both mainline U-Boot and Barebox bootloaders accept the same format of aliases,
which is 'ethernetX', where X stands for an interface number.
Other platforms in the mainline Linux, that comprise ethernet references in
'/aliases' node (like various flavours of imx or sunXi), follow the naming
scheme described above.
This commit ajusts ethernet aliases of Marvell Armada 38x SoC to be properly
recognized by bootloaders' MAC address fixup routines.

The CA9 MPcore SoC Control block is a set of registers that allows to
configure certain internal aspects of the core blocks of the SoC
(Cortex-A9, L2 cache controller, etc.). In most cases, the default
values are fine so they aren't many reasons to touch those registers,
but there is one exception: to support cpuidle on Armada 38x, we need
to modify the value of the CA9 MPcore Reset Control register.
Therefore, this commit adds a new Device Tree binding for this
hardware block, and uses this new binding for the Armada 38x Device
Tree file.

Wildcards in compatible strings should be avoid. "marvell,armada38x"
was recently introduced but was not yet used.
The armada 385 SoC is a superset of the armada 380 SoC (with more CPUs
and more PCIe slots). So this patch replaces the use of
"marvell,armada38x" by the "marvell,armada380" string.

Back when the Armada 370 and Armada XP initial support was introduced,
the only way to pass the clock frequency to the of_serial driver was
through a clock-frequency Device Tree property.
Thanks to 0bbeb3c3e8 ('of serial port
driver - add clk_get_rate() support'), it is possible to use the
standard 'clocks' DT property to reference the clock used for a
particular UART controller. This clock is then used by the of_serial
driver to retrieve the clock rate.
This commit modifies the SoC-level Device Tree files of Armada 370,
Armada XP, Armada 375 and Armada 38x to use this possibility. Since
there is no gatable clock for the UART controllers, we simply
reference the TCLK, which is the main SoC clock for the peripherals.

The mvmdio driver accesses some register of the Ethernet unit. It
therefore takes a reference and enables a clock. However, on Armada
38x, no clock specification was given in the Device Tree, which leads
the mvmdio driver to fail when being used as a module and loaded
before the mvneta driver: it tries to access a register from a
hardware unit that isn't clocked.

* Device Bus
* Clocks
* Interrupt controllers: GIC and MPIC
* GPIO controllers
* I2C buses
