The device is powered by the Exynos 5250 SoC. The bindings for the notification led are already in the linux-next tree and can be found here: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/tree/Documentation/devicetree/bindings/leds/ams,as3668.yaml 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 v4: - Changed copyright years to 2026 - Rearranged includes - Added comments to bmp180 voltage sources - Refactored serial2 output - Rearranged multiple properties of nodes. (@krzk) - Rearranged nodes and subnodes. (@krzk) (@david) - Fixed mismatch with firmware address. - Fixed dtb check errors - Added cpu1 power supply node. - Renamed multiple subnodes. - Removed i2c_0 for now as it isn't used. - Fixed wifi interrupt. - Added empty lines where applicable. (@krzk) (@david) - Deactivated serial_1 for now. - Link to v3: https://lore.kernel.org/r/20251215-lat3st-staging-v3-0-2e4914b64dd8@timmermann.space 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.
