Names are based on the pins they connect to, so yes. The flags cell will make it clear it is a GPIO output. > I really do not understand this kind of thinking and making every device > tree description totally illogical and inconsistent with all other. I don't understand what you mean. When there is a 2nd GPIO used for this binding, what do we call it? 'gpios' doesn't scale. > > > + description: Optional GPIO used for controlling WDI (watchdog input) when WDI bit is not mapped to memory Look at it this way, why do I have to find and read the description here to know what 'gpios' is for when instead, it can be self-describing when I look at the datasheet and the DT to see this is the GPIO connection to WDI signal.
