The CPU nodes should be described as children of "cpus" bus node with
appropriate "reg" properties:
cpus: '#address-cells' is a required property
cpus: '#size-cells' is a required property
cpu: 'device_type' is a required property
cpu: 'reg' is a required property

Using full paths to extend or override a device tree node is error
prone. If there was a typo error, a new node will be created instead of
extending the existing node. This will lead to run-time errors that
could be hard to detect.
A mistyped label on the other hand, will cause a dtc compile error
(during build time).

Fix DTC warnings:
arch/arm/boot/dts/s3c2416-smdk2416.dtb: Warning (avoid_unnecessary_addr_size):
/cpus: unnecessary #address-cells/#size-cells without "ranges" or child "reg" property
arch/arm/boot/dts/s3c2416-smdk2416.dtb: Warning (avoid_unnecessary_addr_size):
/clocks: unnecessary #address-cells/#size-cells without "ranges" or child "reg" property

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 4c9847b7375a ("dt-bindings: Remove leading 0x from bindings notation")

This patch adds alias entries for UART nodes of all SoCs using
samsung-uart compatible UART controllers, so that the dependency on
probe order is removed and deterministic device naming is assured.

This adds the clock controller itself, the xti clock on the smdk2416
as well as the clock references in the individual device nodes.

Definitions in s3c24xx.dtsi are usable for all s3c24xx
SoCs, but some need to be extended with proper compatible
properties, as can be seen in s3c2416.dtsi.
