Yes. The chip's reset is active low.

True.

See previous discussion. Surely there should be _something_ connected to
the output side, but that something might not be relevant for the software
side, so it might be omitted from the device tree.

In fact, I'll submit v3 with the SPDX changes and without exactly this
output port spec which had caused the heated discussion.
