I don't see why there's a dependency on the DRM driver. I'm pretty
sure this would even break simplefb.

I'm not really sure we should put it as a default. We should just

What would be the difference in both cases it would be build as module
since DRM_SUN4I=m for ARM64

I didn't dig further on this. Since ARM64 has is fine with it both
(module and static) may be we can take this.

We wouldn't force it down the throat to every user by default, even
though they have no interest in that driver being compiled into their

No, this build breakage needs to be (reported and) addressed first.

No, this build breakage needs to be (reported and) addressed first.

I think best approach would be that SUN8I_MIXER selects (or depends on?) this 
symbol, since it can't work if there is no DE2 CCU clock present.

This is a runtime dependency, not a build time one. We're not doing it
for any other similar driver, so there's no reason to do it in this
particular case.
