kvmarm-FPEHb7Xf0XXUo1n7N8X6UoWGPAHP3yOg, 'Rahul Sharma'
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

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

Cc: 'Joerg Roedel', 'Kukjin Kim', 'Prathyush',
'Rahul Sharma', 'Subash Patel',
'Grant Grundler', 'Antonios Motakis', kvmarm,
'Sachin Kamat'
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 ?

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.
