Series leds: lp55xx: configure internal charge pump | expand

Commit Message

Maarten Zanders April 7, 2023, 10:23 a.m. UTC 
Add a binding to configure the internal charge pump for lp55xx.

Signed-off-by: Maarten Zanders <maarten.zanders@mind.be>
Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
---

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
    v6: change license type for leds-lp-55xx.h to preferred tag
