Align the pin controller related nodes with dtschema. No functional
change expected.

The Samsung PMIC datasheets describe the interrupt line as active low
with a requirement of acknowledge from the CPU. Without specifying the
interrupt type in Devicetree, kernel might apply some fixed
configuration, not necessarily working for this hardware.

The Devicetree specification expects device node names to have a generic
name, representing the class of a device. Also the convention for node
names is to use hyphens, not underscores.
No functional changes.

Commit 52005dece527 ("ARM: dts: Add assigned clock parents to CMU node
for exynos3250") added assigned clocks under Clock Management Unit to
fix hangs when accessing ISP registers.
However the dtschema expects "clocks" property if "assigned-clocks" are
used. Add reference to input clock to silence the dtschema warnings:
arch/arm/boot/dts/exynos3250-artik5-eval.dt.yaml: clock-controller@10030000: 'clocks' is a dependency of 'assigned-clocks'

The last 8MB of physical memory on Artik520 family boards is reserved for
secure firmware. Adjust the total amount of the memory defined in
exynos3250-artik5.dtsi to match the memory available for the Linux kernel.

Add nodes for GPU (Mali 400) to Exynos3250. This is still limited and
not tested:
1. No dynamic voltage and frequency scaling,
2. Not sure what to do with CLK_G3D clock responsible for gating entire
IP block (it is now being disabled as unused).

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.

S2MPS14 PMIC interrupt line on Exynos3250-based Artik5 evaluation board
has external pull-up resistors, so disable any pull control for it in
controller node. This fixes support for S2MPS14 PMIC interrupts and
enables operation of wakeup from S2MPS14 RTC alarm.

On the Artik 520 module, there is a bcm4354 attached to mshc_1. Enable
it and turn on the regulator used for it, so that both WiFi & Bluetooth
will work.
Verified to work on the Artik 520 evaluation board.

Fix dtc warnings for 'simple_bus_reg' due to leading 0s. Converted using
the following command:
perl -p -i -e 's/\@0+([0-9a-f])/\@$1/g' `find arch/arm/boot/dts -type -f -name '*.dts*'
Dropped changes to ARM, Ltd. boards LED nodes and manually fixed up some
occurrences of uppercase hex.

Behavior should not change, so use the "max-frequency" instead of
"clock-freq-min-max".

The skeleton.dtsi file was removed in ARM64 for different reasons as
explained in commit ("3ebee5a2e141 arm64: dts: kill skeleton.dtsi").
These also applies to ARM and it will also allow to get rid of the
following DTC warnings in the future:
"Node /memory has a reg or ranges property, but no unit name"
The disassembled DTB are almost the same besides an empty chosen
node being removed and nodes reordered, so it should not have
functional changes.

This patch adds the Device Tree source for Samsung ARTIK5 module[1]
based on Exynos3250 SoC. The ARTIK5 module includes the following
devices:
- Application Processor (Samsung Exynos3250)
- WiFi/BT Combo chip (Broadcom4354)
- PMIC (Samsung S2MPS14)
- eMMC (4GB)
- DRAM LPDDR3 (512MB)
- Connectors pin (60 Pins x 3 set)
Also, this patch adds the ARTIK5 evaluation board[2] dts file which includes
the ARTIK5 module[1] and have the devices such as sound codec, sd card port,
ethernet port, uart port and so on.
