This commit adds a pinctrl driver for the CP110 part of the Marvell
Armada 7K and 8K SoCs. The Armada 7K has a single CP110, where almost all
the MPP pins are available. On the other side, the Armada 8K has two
CP110, and the available MPPs are split between the master CP110 (MPPs 32
to 62) and the slave CP110 (MPPs 0 to 31).
The register interface to control the MPPs is however the same as all
other mvebu SoCs, so we can reuse the common pinctrl-mvebu.c logic.

This commit adds a pinctrl driver for the pin-muxing controller found in
the AP806 part of the Marvell Armada 7K and 8K SoCs. Its register
interface is compatible with the one used by previous mvebu pin
controllers, so the common logic in drivers/pinctrl/mvebu/pinctrl-mvebu.c
is used.

Armada 8040 also needs orion pinctrl, and as these symbols are only
selected, there's no need to make them depend on PLAT_ORION.

The Armada 37xx SoC come with 2 pin controllers: one on the south
bridge (managing 28 pins) and one on the north bridge (managing 36 pins).
At the hardware level the controller configure the pins by group and not
pin by pin. This constraint is reflected in the design of the driver:
only the group related functions are implemented.

This commit adds a new pinctrl driver for the Marvell Armada 39x
family of processors, which hooks into the existing infrastructure to
support pin-muxing on Marvell EBU processors. Two variants of the
Armada 39x are supported: 88F6920 (Armada 390) and 88F6928 (Armada
398), which have a few differences in the available functions for
certain pins.

This commit extends the pinctrl mvebu logic with a new driver to cover
Orion5x SoC. It supports the definitions for the 5181l, 5182 and 5281
variants of Orion5x, which are the three ones supported by the old
style MPP code in arch/arm/mach-orion5x/.

Dove pinctrl uses some global config registers to control pins.
This patch requests a syscon regmap for those registers. As this
changes DT to driver requirements, fallback to a self-registered
regmap with hardcoded resources, if the corresponding syscon DT
node is missing. Also, WARN about old DT binding usage to encourage
users to update their DTBs.

The Marvell Armada 380/385 are new ARM SoCs from Marvell, part of the
mvebu family, but using a Cortex-A9 CPU core. In terms of pin-muxing,
it is similar to Armada 370 and XP for the register layout, only
different in the number of available pins and their
functions. Therefore, we simply use the existing
drivers/pinctrl/mvebu/ infrastructure, with no other changes that the
list of pins and corresponding functions.

Like the spear platform, the mvebu platform has multiple files: one
core file, and then one file per SoC family. More files will be added
later, as support for mach-orion5x and mach-mv78xx0 SoCs is added to
pinctrl-mvebu. For those reasons, having a separate subdirectory,
drivers/pinctrl/mvebu/ makes sense, and it had already been suggested
by Linus Wallej when the driver was originally submitted.
