There's a WCN6855 WiFi/Bluetooth module on an M.2 card. To make Bluetooth work, we need to define the necessary device tree nodes, including UART configuration and power supplies.
Since there is no standard M.2 binding in the device tree at present, the PMU is described using dedicated PMU nodes to represent the internal regulators required by the module.
The 3.3V supply for the module is assumed to come directly from the main board supply, which is 12V. To model this in the device tree, we add a fixed 12V regulator node as the DC-IN source and connect it to the 3.3V regulator node.

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: attempting to guess base-commit... Base: tags/next-20251107 (exact match) Base: tags/next-20251107 (use --merge-base to override)
If this is not the correct base, please add 'base-commit' tag (or use b4 which does this automatically)
