clk: samsung: Add support for EPLL on exynos5410 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.
