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 bindings for the notification led are already 
in the kernel mailing list, got recently applied 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.

Changes in v3:
 - Added a better patch description for firmware patch. (@krzk)
 - Reorganized nodes in DT. (@krzk)
 - Fixed memory node to use separate entries. (@krzk)
 - Renamed pwrseq node. (@krzk)
 - Fixed firmware checking for old dt compatible string. (@pavel)
 - Link to v2: https://lore.kernel.org/all/20251125-google-manta-v2-0-0f097cfff39c@timmermann.space/
Changes in v2:
 - Renamed to google-manta (@krzk)
 - Link to v1: https://lore.kernel.org/all/20251120144018.961604-2-linux@timmermann.space/

That's the posting, if you wanted to convince me, you could link to
actual commits in maintainer's tree.

Please ping me when this reaches next.

Best regards,

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: base-commit d5f0e9098499869354aacb5b080f602f0399d396 not known, ignoring
 Base: attempting to guess base-commit...
 Base: tags/next-20251215 (exact match)
 Base: tags/next-20251215 (use --merge-base to override)

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