| |
Now that the driver makes use of `__clk_is_enabled()` in order to know whether a `clk_disable_unprepare()` is needed or not on the GCLK, a new dependency has been introduced: COMMON_CLK. If this `CONFIG_COMMON_CLK` is not enabled, whatever config may have this driver enabled without COMMON_CLK then an undefined reference to `__clk_is_enabled()` will be issued by the linker.
Thus, make sure that, unless `CONFIG_COMMON_CLK` is enabled, this driver is not compiled.
