Okay, lets get some stuff moving! I need a software man!
Since Sailfish has the I2C_HID driver built into the kernel and the TCA8424 is I2C_HID compliant, it should be do-able to connect the dots.
I imagine the phone wants to know that:
-what address the chip is on
-the chip is a keyboard
-it should listen to the interrupt line and then read out the key
-key-mapping in the phone? (there is a keyboard mapped on the chip)
-pushing the input to Mallit

Okay, no more need of external 3.3v power source!
Vdd on
echo 1 > /sys/devices/platform/reg-userspace-consumer.0/state
Vdd off
echo 0 > /sys/devices/platform/reg-userspace-consumer.0/state
Now it really is just a software issue! Feel free to jump in!

I emailed Developer Care for some help on the software side, hope they can help!
Anyway, I opened a donate account. When I have a proof-of-concept ready in the very near future, I will design and order some development PCB's! They will probably cost some 30-40 euro's a piece. Also I have invested pretty heavily in the TCA8424 and its evalutation module.. :-)

While I am waiting ducks for either Jolla to release some I2C documentation ór some I2C software expert from tmo, I've been looking into this:
