[Arm-netbook] EOMA68 libre laptop PCB3 revision 2 walkthrough

quite a long video in this one, where i'm going over the component
selection, component placement, knock-on effect on the casework and so
on.  i'm going to need some help with the schematics on this one, as
there is quite a lot that needs to be integrated and double-checked,
especially the GPIO: all these ICs weren't really designed to be put
together, they don't have proper IO VREF inputs (unlike e.g. the
SN75LVDS83b or many of the I2C EEPROMs), they're Open-Drain and to be
honest i really don't get it how things that are 1.8v, or 3.3v, or
blah-blah voltage are supposed to work.

so i need some help here!  the schematics as a PDF have been
auto-generated, and are at
