I tried to run driver recently created by @korli, but I can’t manage to make it loaded.
I use Haiku hrev54028 and I created i2c_drivers.hpkg package with following contents:
add-ons/kernel/bus_managers/i2c
add-ons/kernel/busses/i2c/pch_i2c
There are no i2c records in syslog and listimage. Reboot and ls -R /dev don’t help.
