opp: Add more resource-managed variants of dev_pm_opp_of_add_table()
Add resource-managed variants of dev_pm_opp_of_add_table_indexed() and dev_pm_opp_of_add_table_noclk(), allowing drivers to remove boilerplate code. Signed-off-by: Dmitry Osipenko <digetx@gmail.com> [ Viresh: Added underscore to devm_of_add_table_indexed() ] Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org>
