Initially, the meson clock directory only hosted 2 controllers drivers, for meson8 and gxbb. At the time, both used the same set of clock drivers so managing the dependencies was not a big concern. Since this ancient time, entropy did its job, controllers with different requirement and specific clock drivers have been added. Unfortunately, we did not do a great job at managing the dependencies between the controllers and the different clock drivers. Some drivers, such as clk-phase or vid-pll-div, are compiled even if they are useless on the target (meson8). As we are adding new controllers, we need to be able to pick a driver w/o pulling the whole thing. The patch aims to clean things up by: * providing a dedicated CONFIG_ for each clock drivers * allowing clock drivers to be compiled as a modules, if possible * stating explicitly which drivers are required by each controller.
