Sylwester Nawrocki be95d2c7d9 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.

Chanwoo Choi ba9d05d972 clk: samsung: exynos5410: Use samsung_cmu_register_one() to simplify code
This patch uses the samsung_cmu_register_one() to simplify code
and move the pll/mux/div/gate data to initconst section.

Stephen Boyd 6f1ed07a14 clk: samsung: Properly include clk.h and clkdev.h
Clock provider drivers generally shouldn't include clk.h because
it's the consumer API. Only include clk.h in files that are
using it. The clkdev.h header isn't always used either, so remove
it and add in slab.h where files were relying on it to include
slab for them.

Sylwester Nawrocki d5e136a21b clk: samsung: Register clk provider only after registering its all clocks
Ensure the clock provider is not registered until after all its related
clocks were created and are ready to use. Currently there are races
possible and any (of_)clk_get() call right after a clock provider's
clk_init_cb callback call may fail.
