Subject: [PATCH v9 05/16] clk: exynos: add gate clock descriptions of System MMU

This adds gate clocks of all System MMUs and their master IPs
that are not apeared in clk-exynos5250.c
Also fixes GATE_IP_ACP to 0x18800 and changed GATE_DA to GATE
for System MMU clocks in clk-exynos4.c

Why are the smmu clocks' parent clocks removed ? Shouldn't both the gscaler
gate clock and the gscaler smmu clock be still same, as it is in case of
exynos4 ?

I agree with Sylwester.

In fact, it is not a valid clock setup. A valid clock must be either root
clock (indicated by appropriate clock flag and specified frequency) or have
a valid parent.

I thought that it does not require parent clock since it is just a gating clock.
Let me check it again.
