Subject: [PATCH v2 0/3] Add basic device tree support for the Axis ARTPEC-9
 SoC

Add basic device tree support for the Axis ARTPEC-9 SoC
which contains 6-core Cortex-A55 CPU and other several IPs.
This SoC is an Axis-designed chipset used in surveillance camera products.

This ARTPEC-9 SoC has a variety of Samsung-specific IP blocks and
Axis-specific IP blocks and SoC is manufactured by Samsung Foundry.

This patch series includes below changes:
- Bindings document update for ARTPEC-9 board (patch #1)
- Device tree for ARTPEC-9 board (patch #2 and #3)

The patch series has been tested on the ARTPEC-9 EVB with
Linux Samsung SoC tree (for-next branch) and intended
to be merged via the `arm-soc` tree.

Pinctrl and UART DT-bindings are present in another patches which are listed below:

Changes in v2:
- Decouple the device tree related patches which was present in v1 (Patch #5 to #7)
  Device tree related patches will be sent in separate series.
