Using the lowlevel debug uart is a corner case - even more so in a

Exynos5800 clock structure is mostly similar to 5420 with only
a small delta changes. So the 5420 clock file is re-used for
5800 also. The common clocks for both are seggreagated and few
clocks which are different for both are separately initialized.Signed-off-by: Alim Akhtar

G2D power domain also controls the CMU block of G2D. Since
clock registers can be accessed anytime for viewing
clk_summary, it can cause a system crash if g2d power domain
is disabled.Signed-off-by: Arun Kumar K

MAU powerdomain provides clocks for Audio sub-system block.
This block comprises of the I2S audio controller, audio DMA
blocks and Audio sub-system clock registers.Right now, there is no way to hook up power-domains with
clock providers. During late boot when this power-domain
gets disabled, we get following external abort.Unhandled fault: imprecise external abort (0x1406) at 0x00000000
