So we end up with everyone needing a "ready" call in each sub-driver
back into the main driver... this makes it impossible to write a
generic subcomponent driver which is not tied in any way to the
main driver.

That is quite some restriction, and would prevent, for example, the
TDA998x driver being used both with Armada DRM, tilcdc and any other
driver.

So, while your solution may work for exynos, it's not suitable for
general use.
