On a similar note to the comment about the platform patch, I think
it would be good to extend the DT binding in a way that allows
you to describe the differences between the SoCs without having
to change the driver every time a new model comes out.

We still have to maintain backwards compatibility with the
existing bindings I suppose, but I'd rather not see new ones
added like this. I realize that there is a tradeoff between
having too much information in DT when it is always fixed, and
having too much hardcoded in the driver, and at some point there
was a conscious decision to do it like this, but I fear the
tradeoff has changed with the number of EXYNOS implementations
that really only differ in their pin banks.
