My intention was that by saying it is connected to the RESET_N bin the active state is covered. I personally always get a little confused when talking about reset lines. The _N denotes that the line is active low but because it is a reset line writing 1 releases the reset so from a what-the-user-wants perspective it's active high. dt-binding-wise what we want here is GPIO_ACTIVE_HIGH, as in the driver writes 1 to release reset so don't do any polarity inversion. I'd be happy do add something to that effect in a v3 but I actually felt saying the gpio is connected to RESET_N was less ambiguous.
