This patch series migrates Exynos4 clock support to common clock framework.
The first patch in this series removes the existing Exynos4 clock support
that uses the Samsung specific clock framework. The second patch in this

In order to support cpuidle through mcpm, suspend and powered-up
callbacks are required in mcpm platform code.
Hence populate the same callbacks.

Exynos5420 is big.Little Soc. It uses cpuidle-big-litle generic cpuidle driver.
Hence do not allow exynos cpuidle driver registration for Exynos5420.

And can you please resend the patch? So that it shows up in Patchwork,
for example?
Yes i will resend it again.

In menu_select function we check for correction factor every time.
If it is zero we are initializing to unity. Hence move it to init function
and initialise by unity, hence avoid repeated comparisons.
