  This change is incompatible with older kernels because it requires the
clock controller driver, but I think that's acceptable because WPCM450
support is generally still in an early phase.

This patch is currently only for demonstration purposes, as it will
break the build if applied in parallel (going through different
maintainer trees) with the other patches in this series.
I will resend it once the other patches have been merged.

v2-v5:
- no changes
