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@xxxxxxxxx/ 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.
