FOSS Pinephone keyboard firmware effort

[megous]

I'm working on a project to make a flashing tool for pinephone keyboard's firmware, and to make a FOSS firmware compilable by sdcc.

My notes are here: https://xnux.eu/log/#035 (+ some general notes on the current keyboard design)

Thoughts (and prayers ) welcome.

Is this similar to the QMK or other easy to hack FOSS keyboard firmwares used mostly for mechanical keyboard enthusiasts?
Also, inside the keyboard are there internal pins or pads that we can access the shift register(and probably add another to multiplex more ports) to hack-on more I2C stuff like NFC?
