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.
