Can't we have:
compatible = "allwinner,sun4i-a10-i2c", "allwinner,sun4i-i2c";
? And keep the old "allwinner,sun4i-i2c" and extend it with a SoC
specific a10 compatible entry when a distinction is needed?

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Or is my knowledge outdated already?
