Add devicetree bindings to support declaring optional voltage dividers to
the rail outputs of supported digital multiphase regulators. Some
applications require Vout to exceed the voltage range that the Vsense pin
can detect. This binding definition allows users to define the
characteristics of a voltage divider placed between Vout and the Vsense
pin for any rail powered by the device.
These bindings copy the vout-voltage-divider property defined in the
maxim,max20730 bindings schema since it is the best fit for the use case
of scaling hwmon PMBus telemetry. The generic voltage-divider property
used by many iio drivers was determined to be a poor fit because that
schema is tied directly to iio for the purpose of scaling io-channel
voltages and the isl68137 driver is not an iio driver.
New schema file named isil,isl68137.yaml to align with the corresponding
driver name and pre-existing bindings ported from trivial bindings.
However, all new device bindings use renesas as the vendor prefix
since Renesas acquired Intersil and now maintains all documentation
for the devices.

Delta AFC0612DB-F00 fan has to be set to at least 30% PWM duty cycle
to spin up from a stopped state, and can be afterward throttled down to
lower PWM duty cycle. Introduce support for operating such fans which
need to start at higher PWM duty cycle first and can slow down next.
Document two new DT properties, "fan-stop-to-start-percent" and
"fan-stop-to-start-usec". The former describes the minimum percent
of fan RPM at which it will surely spin up from stopped state. This
value can be found in the fan datasheet and can be converted to PWM
duty cycle easily. The "fan-stop-to-start-usec" describes the minimum
time in microseconds for which the fan has to be set to stopped state
start RPM for the fan to surely spin up.
