COMMON_CLK is a user-selectable option with its own dependencies. The
most important dependency is !HAVE_LEGACY_CLK. User-selectable drivers
should not select COMMON_CLK because they will create a dependency cycle
and build failures. For example on MIPS a configuration with COMMON_CLK
(selected by SND_SUN8I_CODEC) and HAVE_LEGACY_CLK (selected by
SOC_RT305X) is possible:
WARNING: unmet direct dependencies detected for COMMON_CLK
