The fact that the consumer requires the line to be asserted low is an electronic property of the component, i.e. the panel, and it is just there explaining that if you set it to anything else than active low, you are probably doing something wrong. Should I specify "must be set as active low" instead to make it clear? > > + reset-gpios = <&foo_gpio 0 GPIO_ACTIVE_LOW>; > > This line specifies if ACTIVE HIGH or LOW. Yep we always specify that on the consumer side. Or we should always do that ... but since this panel is by defintion expecting an active low signal, anything else would be an error and that is what I am trying to say in the description.
