It may be a problem of coding correctless, but it's also a maintainability
problem too - it makes it _much_ more difficult to ensure that everything
is correct.

Right, so please make this exynos-specific, because from what I can see it
has no reason to pretend to be generic. As I've already pointed out, it
can't be used in the general case because it ties sub-components directly
to their main driver, which is absolutely absurd. Please keep this
absurdness in exynos and don't spread it around. Thanks.
