PM / devfreq: tegra: add devfreq driver for Tegra Activity Monitor 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 <afrid@nvidia.com> and Mikko Perttunen <mikko.perttunen@kapsi.fi>.

PM / devfreq: tegra: Update to v5 of the submitted patches 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 Signed-off-by: Tomeu Vizoso <tomeu.vizoso@collabora.com> CC: Alex Frid <afrid@nvidia.com> CC: Mikko Perttunen <mikko.perttunen@kapsi.fi> [Added const to device ID by MyungJoo] Signed-off-by: MyungJoo Ham <myungjoo.ham@samsung.com>

PM / devfreq: tegra: Update to v5 of the submitted patches 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 Signed-off-by: Tomeu Vizoso <tomeu.vizoso@collabora.com> CC: Alex Frid <afrid@nvidia.com> CC: Mikko Perttunen <mikko.perttunen@kapsi.fi> [Added const to device ID by MyungJoo] Signed-off-by: MyungJoo Ham <myungjoo.ham@samsung.com>

PM / devfreq: tegra: add devfreq driver for Tegra Activity Monitor 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.

PM / OPP: Update OPP users to put reference This patch updates dev_pm_opp_find_freq_*() routines to get a reference to the OPPs returned by them. Also updates the users of dev_pm_opp_find_freq_*() routines to call dev_pm_opp_put() after they are done using the OPPs. As it is guaranteed the that OPPs wouldn't get freed while being used, the RCU read side locking present with the users isn't required anymore. Drop it as well. This patch also updates all users of devfreq_recommended_opp() which was returning an OPP received from the OPP core. Note that some of the OPP core routines have gained rcu_read_{lock|unlock}() calls, as those still use RCU specific APIs within them.

PM / devfreq: tegra: add devfreq driver for Tegra Activity Monitor 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.

PM / devfreq: tegra: Update to v5 of the submitted patches 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 Signed-off-by: Tomeu Vizoso <tomeu.vizoso@collabora.com> CC: Alex Frid <afrid@nvidia.com> CC: Mikko Perttunen <mikko.perttunen@kapsi.fi> [Added const to device ID by MyungJoo] Signed-off-by: MyungJoo Ham <myungjoo.ham@samsung.com>
