Hi All, In this V4 posting I have fixed suggestions on opp/of and have added the implementation for scmi-cpufreq driver. This is to support systems where exposed cpu performance controls are more fine-grained that the platform's ability to scale cpus independently. [v4] * Remove unconditional set of opp_table->shared_opp to exclusive * Add implementation for scmi-cpufreq * Change subject These patches are on top of: next-20201201 + Lukasz Luba's patches (waiting for Rafael) [1] [v3] * Remove proposal for new 'cpu-performance-dependencies' as we instead can reuse the opp table. * Update documentation for devicetree/bindings/opp * Minor changes within opp to support empty opp table * Rework the RFC by adding a second proposal [v2] * Fix errors when running make dt_binding_check * Improve commit message description for the dt-binding * Add RFC for implementation in cpufreq-core and one of its drivers. Nicola Mazzucato (3): dt-bindings/opp: Update documentation for opp-shared opp/of: Allow empty opp-table with opp-shared scmi-cpufreq: get opp_shared_cpus from opp-v2 for EM Sudeep Holla (1): cpufreq: blacklist Arm Vexpress platforms in cpufreq-dt-platdev Documentation/devicetree/bindings/opp/opp.txt | 53 +++++++++++++++++++ drivers/cpufreq/cpufreq-dt-platdev.c | 2 + drivers/cpufreq/scmi-cpufreq.c | 51 ++++++++++++------ drivers/opp/of.c | 7 ++- 4 files changed, 95 insertions(+), 18 deletions(-) [1] https://lore.kernel.org/linux-pm/20201124104346.27167-1-lukasz.luba@arm.com/
