According to the comment added to exynos_dt_pmu_match[] in commit
8b283c02 ("ARM: exynos4/5: convert pmu wakeup to stacked domains"),
the RTC is not able to wake up the system through the PMU on Exynos5410,
unlike Exynos5420.

However, when the RTC DT node got added, it was a straight copy of
the Exynos5420 node, which now causes a warning from dtc.

This removes the incorrect interrupt-parent, which should get the
interrupt working and avoid the warning.

This reverts commit 6737b081.

Unlike on Exynos5420-family, on Exynos5410 the PMU is not an interrupt
controller so it should not handle interrupts of RTC.  The DTC warning
(addressed by mentioned commit) should be fixed by not routing RTC
interrupts to PMU.

In preparation for the introduction of more than 2 CPs in upcoming

One concept of Marvell Armada 7K/8K SoCs is that they are made of HW
blocks composed of a variety of IPs (network, PCIe, SATA, XOR, SPI,
I2C, etc.), and those HW blocks can be duplicated several times within
a given SoC. The Armada 7K SoC has a single CP110 (so no duplication),
while the Armada 8K SoC has two CP110. In the future, SoCs with more
than 2 CP110s will be introduced.

In current kernel versions, the master CP110 is described in
armada-cp110-master.dtsi and the slave CP110 is described in
armada-cp110-slave.dtsi. Those files are basically exactly the same,
since they describe the same hardware. They only have a few
differences:

 - Base address of the registers is different for the "config-space"

 - Base address of the PCIe registers, MEM, CONF and IO areas were
   different

 - Labels (and phandles pointing to them) of the nodes were different
   ("cpm" prefix in the master CP, "cps" prefix in the slave CP)

This duplication issue has been discussed at the DT workshop [1] in
Prague last October, and we presented on this topic [2]. The solution
of using the C pre-processor to avoid this duplication has been
validated by the people present in this DT workshop, and this patch
simply implements what has been presented.

We handle differences between the master CP and slave CP description
using the C pre-processor, by defining a set of macros with different
values armada-cp110.dtsi is included to instantiate one of the master
or slave CP110.

There are a few aspects that deserve additional explanations:

 - PCIe needs to be handled separately because it is not part of the
   config-space {...} node, since it has registers outside of the
   range covered by config-space {...}.

 - We need to defined CP110_BASE, CP110_PCIEx_BASE without 0x, because
   they are used for the unit address part of some DT nodes. But since
   they are also used for the "reg" property of the same nodes, we
   have an ADDRESSIFY() macro that prepends 0x to those values.

We compared the resulting .dtb for armada-8040-db.dtb before and after
this patch is applied, and the result is exactly the same, except for
a few differences:

 - the SDHCI controller that was only described in the master CP110 is
   now also described in the slave CP110. Even though the SDHCI
   controller from the slave CP110 is indeed not usable (as it isn't
   wired to the outside world) it is technically part of the silicon,
   and therefore it is reasonable to also describe it to be part of
   the slave CP110. In addition, if we wanted to get this correct for
   the SDHCI controller, we should also do it for the NAND controller,
   for which the situation is even more complicated: in a single CP110
   configuration (Armada 7K), the usable NAND controller is in the
   master CP110, while in a dual CP110 configuration (Armada 8K), the
   usable NAND controller is in the slave CP110. Since that would add
   a lot of additional complexity for no good reason, and since the IP
   blocks are in fact really present in both CPs, we simply describe
   them in both CPs at the DT level.

 - the cp110-master and cp110-slave nodes are now named cpm and
   cps. We could have kept cp110-master and cp110-slave, but that
   would have required adding another CP110_xyz define, which didn't
   seem very useful.

Note that this commit also gets rid of the armada-cp110-master.dtsi
and armada-cp110-slave.dtsi files, as future SoCs will have more than
2 CPs. Instead, we instantiate the CPs directly from the SoC-specific
.dtsi files, i.e armada-70x0.dtsi and armada-80x0.dtsi.

We are currently using the cell-index DT property to assign SPI bus
numbers. This property is specific to the spi-orion driver, and
requires each SPI controller to have a unique ID defined in the Device
Tree.

As we are about to merge armada-cp110-master.dtsi and
armada-cp110-slave.dtsi into a single file, those cell-index
properties that differ between the master CP110 and the slave CP110
are a difference that would have to be handled.

In order to avoid this, we switch to using the "aliases" DT node to
assign a unique number to each SPI controller. This is more generic,
and directly handled by the SPI core.

MPP7 is currently muxed as "gpio", but this function doesn't exist for
MPP7, only "gpo" is available. This causes the following error:

kirkwood-pinctrl f1010000.pin-controller: unsupported function gpio on pin mpp7
pinctrl core: failed to register map default (6): invalid type given
kirkwood-pinctrl f1010000.pin-controller: error claiming hogs: -22

kirkwood-pinctrl f1010000.pin-controller: unable to register pinctrl driver
kirkwood-pinctrl: probe of f1010000.pin-controller failed with error -22

So the pinctrl driver is not probed, all device drivers (including the
UART driver) do a -EPROBE_DEFER, and therefore the system doesn't
really boot (well, it boots, but with no UART, and no devices that
require pin-muxing).

Back when the Device Tree file for this board was introduced, the
definition was already wrong. The pinctrl driver also always described
as "gpo" this function for MPP7. However, between Linux 4.10 and 4.11,
a hog pin failing to be muxed was turned from a simple warning to a
hard error that caused the entire pinctrl driver probe to bail
out. This is probably the result of commit 61187142 ("pinctrl:
core: Fix pinctrl_register_and_init() with pinctrl_enable()").

This commit fixes the Device Tree to use the proper "gpo" function for
MPP7, which fixes the boot of OpenBlocks A7, which was broken since
Linux 4.11.

The EB MP board probably has a character LCD but the board manual does
not really state which IRQ it has assigned to this device. The invalid
assignment was a mistake by me during submission of the DTSI where I was
looking for the reference, didn't find it and didn't fill it in.

Delete this for now: it can probably be fixed but that requires access
to the actual board for some trial-and-error experiments.

Allwinner DT64 changes for 4.16

There are two important changes in this round.

The first removes the redundant pinctrl setting for the MMC card detect
GPIO. We are moving to strict pinctrl/GPIO exclusion, i.e. GPIO usage
will block other pin muxing usage, and vice versa. The usage of pinmux
for guarding GPIO pins in the device tree prevents us from doing so.
This is part of an ongoing effort to clean up the existing device trees.

The other important change enables the PMIC on the Orangepi Win. The
PMIC provides power to most of the external onboard peripherals.
Enabling it will allow us to enable Ethernet or WiFi support later on.

The remaining changes in this round enable some peripheral, such as
Ethernet, an external WiFi chip, or LEDs.

Allwinner DT changes for 4.16

A random assortment of improvements.

GPIO device nodes are added for the AXP813/AXP818 PMICs, meaning we can
finally use the GPIO pins on the PMICs. The LDOs on the GPIO pins can
also be properly muxed and guarded.

EMAC Ethernet support is enabled for more H3 boards, and also for the
A83T, following the return of the bindings in 4.15, after a last minute
revert in 4.13. This will make the H3/A83T boards much more useful in
headless applications.

Two new boards are introduced. The Orange Pi R1 is a small board with
two Ethernet interfaces (one EMAC-based and one USB-based) and a WiFi
chip. This board is fully supported, with the exception of TV-out on
the expansion header, which will not be enabled by default. The WiFi
chip (RTL8189FTV) requires an out-of-tree driver. The Libre Computer
Board ALL-H3-CC H3 version is a newcomer to the Allwinner SBC space,
which was mostly represented by a bunch of fruit-Pis. It is mostly
supported, with the exception of HDMI and camera sensor interface,
which have not been implemented yet.

Two minor patches enable the audio codec on the A13 Olinuxino, and
HDMI output on the pcDuino3 Nano.
