There are two common DTSI files for Exynos5422 Odroid XU3 family of
boards. One is shared between all of them (XU3, XU3-Lite, XU4 and HC1)
and the second skips HC1. Document this in the files.

Add SD card write-protect pin configuration to be sure that it will be
properly pulled down to indicate write access.

From Odroid XU3/XU4/HC1 schematics the LDO13 regulator for SD2, can be
set on 1.8V or 2.8V so the minimal value should be fixed to 1.8V. This
is necessary to support UHS-I tuning (otherwise card won't be detected
during boot).

The bindings for s2mps11/s5m8767 clocks driver require a compatible for
clocks node. Parent MFD sec-core driver will also use it when
instantiating children.
The compatible is not needed for proper working because device will be
anyway created by parent MFD device. Add it for correctness.

The LDO28 is used only on Odroid XU3 for Display Port. Define it so DTS
will describe entire hardware.
Depending on bootloader behavior this might affect the Display Port
because none of drivers are enabling it. By default it is off in S2MPS11
PMIC reset values. However it could be enabled by bootloader so in such
case kernel will later disable it as unused regulator.

Disable unused PMIC regulators on Exynos5422 Odroid boards to reduce
energy used. According to schematics:
1. LDO12, LDO16 and LDO24 are not connected,
2. LDO26 is not used on Odroid HC1.

Improve the DTS files by removing all the leading "0x" and zeros to fix the
following dtc warnings:
Warning (unit_address_format): Node /XXX unit name should not have leading "0x"
Warning (unit_address_format): Node /XXX unit name should not have leading 0s
Converted using the following command:
find arch/arm/boot/dts -type f \( -iname "*.dts" -o -iname "*.dtsi" \) -exec sed -i \
-e "s/@\([0-9a-fA-FxX\.;:#]\+\)\s*{/@\L\1 {/g" -e "s/@0x\(.*\) {/@\1 \
{/g" -e "s/@0\+\(.\+\) {/@\1 {/g" {} +
For simplicity, two sed expressions were used to solve each warnings separately.
To make the regex expression more robust a few other issues were resolved,
namely setting unit-address to lower case, and adding a whitespace before the
the opening curly brace: https://elinux.org/Device_Tree_Linux#Linux_conventions
This will solve also a side effect warning:
Warning (simple_bus_reg): Node /XXX@<UPPER> simple-bus unit address format error, expected "<lower>"
This is a follow up to commit 4c9847b737 ("dt-bindings: Remove leading 0x from bindings notation")

Looking at the schematic, LDO15 and LDO17 are tied as a power source of a
builtin network chipset. Correct voltage on LDO15 to 3.3V and the name
of LDO17 to "vdd_ldo17".

Odroid HC1 board is based on Odroid XU4 board, but it has no HDMI,
no eMMC, no built-in USB3.0 hub, no extension port pins, and no GPIO
button. USB3.0 ports are used for built-in JMicron USB to SATA bridge
and Gigabit R8152 ethernet chips. HC1 uses only passive cooling.
