For the chips that are supported upstream right now, that would work.
However, I'm not sure that life will be quite so linear in the future.
In other words, what is "or later" for, say, the SDHCI controller may
not be the same as what is "or later" for, say, the I2C controller.
(feel free to substitute arbitrary HW modules into that statement).
