    clk: samsung: Add support for EPLL on exynos5410 · be95d2c7
    Sylwester Nawrocki authored
    This patch adds code instantiating the EPLL, which is used as the
    audio subsystem's root clock.
    The requirement to specify the external root clock in clocks property
    is documented.  Having the consumer 'clocks' property ensures proper
    initialization order by explicitly specifying dependencies in DT.
    It prevents situations when the SoC's clock controller driver has
    initialized, the external oscillator clock is not yet registered
    and setting clock frequencies through assigned-clock-rates property
    doesn't work properly due to unknown external oscillator frequency.
