Although it's a 14-pin *connector*, only 8 *signals* appear on it. And
two are shared with the "signal interface" of the power connector, so you

It's probably considered better form to access it via /dev/elan-mmcr,
though admittedly one needs to dig through more "documentation" to do it
that way. If the mmcr driver supports mmap, only the setup would be
