2b69a67389 watchdog: Add support for Armada 37xx CPU watchdog
This adds support for the CPU watchdog found on Marvell Armada 37xx
SoCs.

There are 4 counters which can be set as CPU watchdog counters.
This driver uses the second counter (ID 1, counting from 0)
(Marvell's Linux also uses second counter by default).
In the future it could be adapted to use other counters, with
definition in the device tree.

dbbd5bdd27 spi: mvebu_a3700_spi: Use Armada 37xx clk driver for SPI clock frequency
Since now we have driver for clocks on Armada 37xx, use it to determine
SQF clock frequency for the SPI driver.

Also change the default config files for Armada 37xx devices so that
the clock driver is enabled by default, otherwise the SPI driver cannot
be enabled.

82a248df9a driver: clk: Add support for clocks on Armada 37xx
The drivers are based on Linux driver by Gregory Clement.

The TBG clocks support only the .get_rate method.
  - since setting rate is not supported, the driver computes the rates
    when probing and so subsequent calls to the .get_rate method do not
    read the corresponding registers again

The peripheral clocks support methods .get_rate, .enable and .disable.

  - the .set_parent method theoretically could be supported on some clocks
    (the parent would have to be one of the TBG clocks)

  - the .set_rate method would have to try all the divider values to find
    the best approximation of a given rate, and it doesn't seem like
    this should be needed in U-Boot, therefore not implemented

22f418935b phy: marvell: a3700: Use comphy_mux on Armada 37xx.
Lane 0 supports SGMII1 and USB3.
Lane 1 supports SGMII0 and PEX0.
Lane 2 supports SATA0 and USB3.

This is needed for Armada 37xx.

This introduces new device tree bindings. AFAIK there is currently no
driver for Armada 37xx comphy in Linux. When such a driver will be
pushed into Linux, this will need to be rewritten accordingly.

30aecc02f7 arm64: a37xx: dts: Correct mpp definitions
This patch corrects below mpp definitions for armada 3720 DB board
and ESPRESSOBin board:
- "smi" pins group is added and "smi" function is set for eth0;
- Now pcie pins are used as gpio to implement PCIe function in
  hardware, so "pcie" group function is changed to "gpio".

8aecbcd166 arm64: a37xx: dts: Fix the number of GPIO on south bridge
The number of pins in South Bridge is 30 and not 29. There is a fix for
the driver for the pinctrl, but a fix is also need at device tree level
for the GPIO.

5cb7b79558 arm64: mvebu: Add pinctrl nodes for Armada 3700
Add the nodes for the two pin controller present in the Armada 37xx SoCs.

Initially the node was named gpio1 using the same name that for the
register range in the datasheet. However renaming it pinctr_nb (nb for
North Bridge) makes more sens.

Minor changes for U-Boot because of the slightly different dts version
done by Stefan Roese.
