The two properties: - max-brightness - default brightness are not really required, so they can be removed from the "required" section. Other changes: - improve the backlight working mode description, in the "description" section - update the example, removing the "max-brightness" and introducing the "brightess-levels" property Signed-off-by: Flavio Suligoi <f.suligoi@xxxxxxx> --- .../bindings/leds/backlight/mps,mp3309c.yaml | 10 ++++------ 1 file changed, 4 insertions(+), 6 deletions(-) diff --git a/Documentation/devicetree/bindings/leds/backlight/mps,mp3309c.yaml b/Documentation/devicetree/bindings/leds/backlight/mps,mp3309c.yaml index 4191e33626f5..527a37368ed7 100644 --- a/Documentation/devicetree/bindings/leds/backlight/mps,mp3309c.yaml +++ b/Documentation/devicetree/bindings/leds/backlight/mps,mp3309c.yaml @@ -14,8 +14,8 @@ description: | programmable switching frequency to optimize efficiency.
