Do you need it to work in interrupt mode, or would it be enough to
use PIO mode at first?
With a CPU running in the GHz range I didn't dare using polling, but
I'll give it a try.
I meant PIO mode of the I2C controller, looking at the datasheet it
supports both that and interrupt/DMA modes.
You could also check that the clock definitions are correct.
Have you made any local device tree modifications?
From a dump of the .dtb file that we build, the i2c controllers seem
to be marked as disabled and don't have clock names defined for them.
