OK, so the housing DT will contain the following for a VGA port...
paul: quite late, here, more tomorrow. summary strategy:
* look at rbpi "hats" and how dtb overlays are done * copy that * rename rbpi "hat" overlay pins 0 to M to "eoma68 pins 1 to 68"
in theory that should be pretty much the entire job, bar removing all multiplexed options other than the 1 specialist function and the GPIO option. where in rbpi base "hat" interface there would be up to 4 multiplexed options per pin (one of which will be GPIO), that must be restricted to "GPIO" and "EOMA68 function", per pin.
that really should be all.
