| |
The MT8173 cpufreq driver can currently only be built-in, but it has a Kconfig dependency on the thermal core. THERMAL can be a loadable module, which in turn makes this driver impossible to build.
It is nicer to make the cpufreq driver a module as well, so this patch turns the option in to a 'tristate' and adapts the dependency accordingly.
The driver has no module_exit() function, so it will continue to not support unloading, but it can be built as a module and loaded at runtime now.
