It doesn't matter, all the i2c busses are missing the pullups.

I guess legacy board code does not set i2c pull-ups either, as we
have that problem since the beginning of time. Anyway, let me first
check if enabling pullups really solves the issue, I hope to test that 
in a couple of hours when I am back home.

Or you can do it yourself, it is just a matter of replacing PIN_INPUT 
with PIN_INPUT_PULLUP in 
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/arch/arm/boot/dts/omap3-n900.dts?id=refs/tags/v4.5#n199 
for all the 3 ic2 busses

Regards,
Ivo
