[PATCH v2 1/1] arm64: dts: qcom: lemans-evk: Enable Bluetooth support

[Wei Deng]

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 module provides a 3.3V supply, which originates from the
main board’s 12V rail. To represent this power hierarchy in the device
tree, add a fixed 12V regulator node as the DC-IN source and link 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-20251112 (exact match)
 Base: tags/next-20251112 (use --merge-base to override)

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