Series leds: lp55xx: configure internal charge pump |

Commit Message

Maarten Zanders Feb. 13, 2023, 10:20 a.m. UTC
  Add a binding to configure the internal charge pump for lp55xx.

Signed-off-by: Maarten Zanders <maarten.zanders@mind.be>
---

Notes:
    v1: implement as bool to disable charge pump
    v2: rewrite to use string configuration, supporting all modes
    v3: simplification by replacing string option by u8 constant,
        removing previous Reviewed-by tags as it's a complete
        rewrite of the patch.
    v4: added notes
    v5: dual license, change property type to u32

While technically it is almost equal to BSD-2, any particular reason for
using different second license than the binding and generic
recommendation (checkpatch)?

Best regards,

No, no specific reason. I'm happy to adapt.

Then please switch to recommended ones. With that:
