Add needed information inside CPU0 for the generic cpufreq-cpu0 driver.
- voltage-tolerance = 1%
It reflects the tolerance for the CPU voltage defined inside the OPP
table. Due to the lack of proper OPP definition, use an arbitrary safe
value.
- clock-latency = 300 us
Approximate worst-case latency to do a full DVFS transition for every
OPPs. Due to the lack of HW information, use an arbitrary safe value.
Note: The term transition-latency will be more accurate to define this
value since the clock transition latency is not the only parameter that
will define the overall DVFS transition.
- operating-points = < kHz - uV >
List of 6 operating points. All of them are using the same voltage
since DVS is not supported in R-CAR Gen2.
- clocks
phandle to the CPU clock source. This clock source is used for all the
2 CortexA15 located inside the same cluster.

As with previous release, this continues to be among the largest branches
we merge, with lots of new contents.
New things for this release are among other things:
- DTSI contents for the new SoCs supported in 3.16 (see SoC pull request)
- Qualcomm APQ8064 and APQ8084 SoCs and eval boards
- Nvidia Jetson TK1 development board (Tegra T124-based)
Two new SoCs that didn't need enough new platform code to stand out
enough for me to notice when writing the SoC tag, but that adds new DT
contents are:
- TI DRA72
- Marvell Berlin 2Q

The r8a7791 has three VSP1 instances, one of them being named VSPS (which
stands for "VSP Standard"). The clock section in the SoC datasheet
misunderstood the abbreviation as meaning VSP System, and named the
corresponding clock VSP1(SY). This mistake has been carried over to the
kernel code.
Fix this by renaming the VSP1_SY clock to VSP1_S.

A large part of the arm-soc patches are nowadays DT changes, adding support
for new SoCs, boards and devices without changing kernel source. The plan
is still to move the devicetree files out of the kernel tree and reduce
the amount of churn going on here, but we keep finding reasons to delay
doing that.
Changes are really all over the place, with little sticking out particularly.
We have contributions from a total of 116 people in this branch.
Unfortunately, the size of this branch also causes a significant number
of conflicts at the moment, typically when subsystem maintainers merge
patches that change the driver at the same time as the dts files. In
most cases this could be avoided because the dts changes are supposed
to be compatible in both ways, and we are asking everyone to send ARM
dts changes through our tree only.
