[PATCH v2 0/4] leds: privacy-led support for devicetree

Posted by Aleksandrs Vinarskis 4 days, 8 hours ago

Re-spin of RFC patch from ~2.5 years ago [1]. v4l2 controls for privacy
LEDs has landed, but the DT part was left out. Introduce missing
dt-bindings, and commonize 'leds' parameter. Finally, add a patch to
enable privacy-led on Lenovo Thinkpad x13s.

With recent inflow of arm64-power laptops (Snapdragon X1E/X1P) which
mostly use MIPI cameras, this feature becomes more desired. Original
rebased patch is still working as expected (with respective DT changes)
on Dell XPS 9345.

Changelog to original series:
- Pick RFC patch, pick R-by, drop RFC-related commit message part
- Add new DT binding to describe generic LED consumer properties
- Rebase and test on X1E laptop

Changes in v2:
- Fixed mailing issue
- Fixed wrong R-by, add my missing sign-off
- Elaborated cover letter/commits descriptions to better describe why
  this is needed, and why trigger-source could not be used instead

  expanded the example
- dt-bindings: added patch to commonize 'leds' from other schemas
- leds: dropped wrapper, dropped exporting of private functions
- dts: added patch to utilize privacy-led on Lenovo Thinkpad x13s
- Link to v1: https://lore.kernel.org/all/010201990a1f5ad8-fc97fc84-9ef9-4a03-bf1c-2d54423c6497-000000@eu-west-1.amazonses.com/
