Subject: [PATCH v3 00/12] OPP API fixes and improvements

Hi,

This series fixes problems and adds features to OPP API that are required
for implementation of a power domain driver for NVIDIA Tegra SoCs.

It is a continuation of [1], where Viresh Kumar asked to factor OPP
patches into a separate series. I factored out the patches into this
series, addressed the previous review comments and re-based patches
on top of [2], which replaced some of my patches that added resource-managed
helpers.

[1] https://patchwork.ozlabs.org/project/linux-tegra/list/?series=221130
[2] https://lore.kernel.org/linux-pm/20210101165507.19486-1-tiny.windzz@gmail.com/

Changelog:

v3: - Reordered patches by importance.

    - Added locking to dev_pm_opp_set_voltage().

    - Reworked "Fix adding OPP entries in a wrong order if rate is unavailable"
      patch, like it was suggested by Viresh Kumar.

    - Reworked "Support set_opp() customization without requiring to use
      regulators" patch, like it was suggested by Viresh Kumar.

      The opp_table->set_opp_data is now allocated by dev_pm_opp_register_set_opp_helper().

      The set_opp_data is refcounted now and can be allocated by any other
      OPP functions if this will become needed in the future for other OPP API
      changes.
