Krzysztof Kozlowski e3c3f19bc6 clk: samsung: exynos3250: Register DMC clk provider
Add clock provider for clocks in DMC domain including EPLL and BPLL. The
DMC clocks are necessary for Exynos3 devfreq driver.

The DMC clock domain uses different address space (0x105C0000) than
standard clock domain (0x10030000 - 0x10050000). The difference is huge
enough to add new DT node for the clock provider, rather than extending
existing address space.

Krzysztof Kozlowski 45c5b0a690 clk: samsung: exynos3250: Enable ARMCLK down feature
Enable ARMCLK down feature on Exynos3250 SoC. The frequency of
ARMCLK will be reduced upon entering idle mode (WFI or WFE).

The feature behaves like very fast cpufreq ondemand governor.

The patch uses simillar settings as Exynos5250 (clk-exynos5250.c),
except it disables clock up feature.

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.

Tomasz Figa 2ce16c5342 clk: samsung: exynos3250: Add clocks using common clock framework
This patch add new the clock drvier of Exynos3250 SoC based on Cortex-A7
using common clock framework. The CMU (Clock Management Unit) of Exynos3250
control PLLs(Phase Locked Loops) and generate system clocks for CPU, buses,
and function clocks for individual IPs.

The CMU of Exynos3250 includes following clock doamins:
- CPU block for Cortex-A7 MPCore processor
- LEFTBUS/RIGHTBUS block
- TOP block for G3D/MFC/LCD0/ISP/CAM/FSYS/MFC/PERIL/PERIR
