[v2,13/16] clk: samsung: exynos4: Reorder registration of mout_vpllsrc

Commit Message

Tomasz Figa Aug. 26, 2013, 5:09 p.m. UTC

Since PLL input frequency must be known before PLL registration,
mout_vpllsrc clock which is a reference clock of VPLL must be registered
before VPLL.

This patch reorders clock registration to register mout_vpllsrc before
VPLL.
