This patch series updates the device tree vendor prefix for
Dialog Semiconductor.

Various methods are currently used throughout the kernel: 'diasemi',
'dialog' and 'dlg'. Others have also been suggested.

This patch set aims to consolidate the usage of the vendor prefix to
use a common standard. The prefix 'dlg' is used.

On r8a7791, i2c6 (aka iic3) doesn't need pinmux, but the koelsch dts
refers to non-existent pinmux configuration data:

pinmux core: sh-pfc does not support function i2c6
sh-pfc e6060000.pfc: invalid function i2c6 in map table

Remove it to fix this.

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.

The CA15 cluster is capable of voltage scaling. Add the regulator
in the i2c6 node, to allow the generic CPUFreq driver to use it.

Enable the i2c6 pin mux and the device node as well since the
da9210 is connected to that bus.

Note: In R-CAR Gen2, each frequency is using the same voltage,
and DVS control is not used. Therefore, this patch set the
voltage(Vmin/Vmax) to 1000mv.
