Subject: [PATCH v4 0/4] CPUFreq: Add support for opp-sharing cpus
Date: Wed,  2 Dec 2020 17:23:52 +0000	[thread overview]
Message-ID: <20201202172356.10508-1-nicola.mazzucato@arm.com> (raw)

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
