b9b28f5254 ARM: shmobile: r8a73a4: add a clock alias for the DMAC in DT mode
Devices, initialised from the Device Tree and from platform code usually
have different names. This patch adds a clock alias for DMAC on r8a73a4
in DT mode.

e4a6a29d12 ARM: shmobile: change dev_id to cpu0 while registering cpu clock
Currently all clkdev registration use "cpufreq-cpu0.0" as dev_id
for cpu clock which refers to virtual platform device. It needs to
be "cpu0" instead which is actual cpu0 device id.

This patch changes the dev_id from "cpufreq-cpu0.0" to "cpu0".

d1c3c959f2 ARM: shmobile: r8a73a4: safeguard against wrong clk_set_rate() uses
clk_set_rate() should only be called with exact rates, returned by
clk_round_rate(). However, it is still good to verify, that the value,
passed to clock's .set_rate() method is at least valid. This patch adds
such a check for the Z-clock on r8a73a4.

This patch adds support for the Z-clock on r8a73a4 SoCs, which is driving
the Cortex A15 core, and a "cpufreq-cpu0" platform device. Adding an
"operating-points" property to the CPU0 DT node and a regulator, this
patch allows platforms to use the generic cpufreq-cpu0 driver to use
SoC's DVFS capabilities.

8d27657286 ARM: shmobile: r8a73a4: wait for completion when kicking the clock
To reconfigure clocks, controlled by FRQCRA and FRQCRB, a kick bit has to
be set and to make sure the setting has taken effect, it has to be read
back repeatedly until it is cleared by the hardware. This patch adds the
waiting part, that was missing until now.
