Pull ARM cpufreq driver changes for v5.9-rc1 from Viresh Kumar:
"Here are the details:
- Adaptive voltage scaling (AVS) support and minor cleanups for
brcmstb driver (Florian Fainelli and Markus Mayer).
- A new tegra driver and cleanup for the existing one (Sumit Gupta and
Jon Hunter).
- Bandwidth level support for Qcom driver along with OPP changes (Sibi
Sankar).
- Cleanups to sti, cpufreq-dt, ap806, CPPC drivers (Viresh Kumar, Lee
Jones, Ivan Kokshaysky, Sven Auhagen, and Xin Hao).
- Make schedutil default governor for ARM (Valentin Schneider).
- Fix dependency issues for imx (Walter Lozano).
- Cleanup around cached_resolved_idx in cpufreq core (Viresh Kumar)."

It is not possible for cached_resolved_idx to be invalid here as the
cpufreq core always sets index to a positive value.
Change its type to unsigned int and fix qcom usage a bit.

Add support to parse optional OPP table attached to the cpu node when
the OPP bandwidth values are populated. This allows for scaling of
DDR/L3 bandwidth levels with frequency change.

The Energy Model framework supports not only CPU devices. Drop the CPU
specific interface with cpumask and add struct device. Add also a return
value, user might use it. This new interface provides easy way to create
a simple Energy Model, which then might be used by e.g. thermal subsystem.

Allow qcom-hw driver to initialize right after the cpufreq and thermal
subsystems are initialised in core_initcall so we get earlier access to
thermal mitigation.

The core count read back from the each domain's look up table serves
as an indicator for the onset of the turbo frequency and not accurate
representation of number of cores in a paticular domain. Update turbo
detection logic accordingly to add support for SM8150 SoCs.

Add support to read the voltage look up table and populate OPP for all
corresponding CPUS for consumers like the energy model could use the
frequency and voltage from the OPP tables. Also update the logic to not add
duplicate OPPs.

subsys_initcall causes problems registering the driver as a thermal
cooling device.
If "faster boot" is the main reason for doing subsys_initcall, this
should be handled in the bootloader or another boot constraint
framework.

The CPUfreq HW present in some QCOM chipsets offloads the steps necessary
for changing the frequency of CPUs. The driver implements the cpufreq
