[PATCH 00/16] Led update for STMicrolectronics boards

[PATCH 00/16] Led update for STMicrolectronics boards

[Patrice Chotard]

This series adds/updates LED nodes for STMicroelectronics boards by
adding new LED nodes and function/color properties.

On STM32 MCUs boards (F4/F7 and H7 series) green LED is
used as heartbeat.

On STM32MP1/2, blue LED is used as heartbeat.

On STM32MP1, red LED is used as status LED.

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: 53c18dc078bb6d9e9dfe2cc0671ab78588c44723 (use --merge-base to override)

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