• dbb0c7c43   PM / devfreq: tegra: Set freq in rate callback ... Browse Code »

  As per the documentation of the devfreq_dev_profile.target callback, set
  the freq argument to the new frequency before returning.

  This caused endless messages like this after recent changes in the core:

  devfreq 6000c800.actmon: Couldn't update frequency transition information.

  drvdata has been set up.

  As the DT bindings don't have an operating-points property any more,
  build the OPP table from the frequencies supported by the EMC clock.

  Now that we have per-user clocks and the possibility to set constraints
  in a clock, set a floor constraint on the EMC clock.

• 11573e913   PM / devfreq: tegra: Update to v5 of the submitted patches ... Browse Code »

  There seemed to be some miscommunication and an old version of the
  submitted patches was merged.

  This commit updates the driver to v5, which had this changelog:

  * Clarify the units of avg_dependency_threshold
  * Remove unused references to platform_device
  * Enable and disable interrupts on governor events
  * Make sure we handle all interrupts for any of the devices we are sampling
  * Move locking to be per-actmon-device

• 6234f3801   PM / devfreq: tegra: add devfreq driver for Tegra Activity Monitor ... Browse Code »

  The ACTMON block can monitor several counters, providing averaging and firing
  interrupts based on watermarking configuration. This implementation monitors
  the MCALL and MCCPU counters to choose an appropriate frequency for the
  external memory clock.

  This patch is based on work by Alex Frid and Mikko
  Perttunen .
