    clk: meson: rework and clean drivers dependencies · 889c2b7e
    Jerome Brunet authored
    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.
