I'd make that:

    -        depends on DRM
    +       depends on COMMON_CLK && DRM && IOMMU_SUPPORT
            depends on ARCH_QCOM || SOC_IMX5 || COMPILE_TEST
    -        depends on IOMMU_SUPPORT
    -       depends on (OF && COMMON_CLK) || COMPILE_TEST
    +       depends on OF || COMPILE_TEST

to keep a better separation between hard and soft dependencies.

Note that the "depends on OF || COMPILE_TEST" can even be
deleted, as the dependency on ARCH_QCOM || SOC_IMX5 implies OF.
