For non-a10, That should be at least

	compatible = "allwinner,sun4i-a13-i2c", "allwinner,sun4i-a10-i2c";

or

	compatible = "allwinner,sun4i-a13-i2c", "allwinner,sun4i-i2c";

depending on the outcome above.

Or is my knowledge outdated already?

Since they are strictly compatible, we don't need to introduce any
different compatible string here.

You never know all errata in advance. From what I know, one should
always use the specfic naming first, and then the generic fallback. So,
in case a distinction is needed later (think errata), then one doesn't
need to change the devicetrees.

And adding a A13-specific compatible wouldn't change anything, because
it does work on at least one revision of them, so if you'd have to
deal with an errata, you'd have to introduce a new compatible for this
revision only anyway.
