1f9c7a691f ARM: shmobile: Add forward declaration of struct clk to silence warning
arch/arm/mach-shmobile/board-genmai-reference.c:23:0:
arch/arm/mach-shmobile/include/mach/clock.h:19:54: warning: 'struct clk' declared inside parameter list [enabled by default]
arch/arm/mach-shmobile/include/mach/clock.h:19:54: warning: its scope is only this definition or declaration, which is probably not what you want [enabled by default]

25f5550f5a ARM: shmobile: Introduce shmobile_clk_workaround()
Introduce a new clock workaround function used by DT reference
code on the mach-shmobile subarchitecture. The new function
shmobile_clk_workaround() is used to configure clkdev to
allow DT and platform devices to coexist. It is possible for
the DT reference board code to also request enabling of the clock
in case the driver does not implement clock control.

f5942c7621 ARM: shmobile: add struct clk_ratio and fixed ratio clock macro
Renesas chip has many clocks inside,
and some of them are using fixed ratio via parent clock.
Current shmobile clock code is using own divX_recalc function
and divX_clk_ops.
This patch can reduce these code
