Where is this documented and do you have a link to the debate?

The archive for the i2c mailing list doesn't show much debate:

https://lore.kernel.org/linux-i2c/?q=%2280+columns%22
https://lore.kernel.org/linux-i2c/?q=%22line+length%22

Perhaps there should be a MAINTAINERS P: entry for this requirement.
