This patch series adds initial support for the google-manta board, known
as Google Nexus 10 to users. The device is powered by
the Exynos 5250 SoC. The notification led driver (as3668) is already 
(tho not applied) in the kernel mailing list and can be found here:
https://lore.kernel.org/linux-leds/20251125114015.355487-1-linux@timmermann.space/

The first two patches add the necessary device tree files and
bindings, while the last patch makes a small modification to
allow CPU1 to boot, as it requires a call to it's underlying firmware.

This first iteration only provides basic support to get the board
up and running and usable via UART and with WiFi support. We will upstream additional 
features in future patches. All patches have been tested on real hardware.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Base: 6a23ae0a96a600d1d12557add110e0bb6e32730c (use --merge-base to override)

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)

Thank you for your patches.

Nothing in the cover letter improved regarding my request - you clearly
need to document, in a very explicit and obvious way, that this uses
bindings where not applied. Drivers don't matter here. I need here list
of bindings this is using which were not yet applied by maintainers.

If there is going to be v3, please be sure you fix the cover letter.

Best regards,
Krzysztof
