It does NOT work for ARM64 defconfig when we try to make CONFIG_MXC_CLK=m, Below are my change, you can see in .config, even all i.MX8 SoCs clock drivers are configured to module, the CONFIG_MXC_CLK is still =y, but the expected result is =m.

But now I got your point you want CONFIG_MXC_CLK default to m once define CONFIG_CLK_IMX8X=m in defconfig. > BTW, all i.MX8 SoCs select MXC_CLK in their kconfig, this patch just does the > same thing for i.MX6/7 in common place. > I just noticed for MX6&7, actually CONFIG_MXC_CLK can't be m otherwise we will meet build break. That means CONFIG_MXC_CLK cannot be configurable by users for non-ARM64 platforms. Thus can't use def_tristate and we still need select it under ARCH_MXC. This lightly lose a bit meaning to make this core library as module. IMHO I'd still prefer to builtin those core libraries rather than convert to module.
