2015-09-11PM / devfreq: tegra: Update governor to use devfreq_update_stats()MyungJoo Ham1-3/+5
Direct invocation of get_dev_status() is no more recommended. Signed-off-by: MyungJoo Ham <[email protected]>
2015-03-31PM / devfreq: tegra: Register governor on module initTomeu Vizoso1-7/+30
So this driver builds as a module. Signed-off-by: Tomeu Vizoso <[email protected]> Signed-off-by: MyungJoo Ham <[email protected]>
2015-03-31PM / devfreq: tegra: Enable interrupts after resuming the devfreq monitorTomeu Vizoso1-2/+2
Signed-off-by: Tomeu Vizoso <[email protected]> Acked-by: MyungJoo Ham <[email protected]>
2015-03-31PM / devfreq: tegra: Set drvdata before enabling the irqTomeu Vizoso1-2/+2
To avoid a race in which the interrupt will be handled before the drvdata has been set up. Signed-off-by: Tomeu Vizoso <[email protected]> Acked-by: MyungJoo Ham <[email protected]>
2015-03-31PM / devfreq: tegra: remove operating-pointsTomeu Vizoso1-6/+6
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. Signed-off-by: Tomeu Vizoso <[email protected]> Acked-by: MyungJoo Ham <[email protected]>
2015-03-31PM / devfreq: tegra: Use clock rate constraintsTomeu Vizoso1-10/+5
Now that we have per-user clocks and the possibility to set constraints in a clock, set a floor constraint on the EMC clock. Signed-off-by: Tomeu Vizoso <[email protected]> Acked-by: MyungJoo Ham <[email protected]>
2015-03-31PM / devfreq: tegra: Update to v5 of the submitted patchesTomeu Vizoso1-204/+253
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 <[email protected]> CC: Alex Frid <[email protected]> CC: Mikko Perttunen <[email protected]> [Added const to device ID by MyungJoo] Signed-off-by: MyungJoo Ham <[email protected]>
2015-01-29PM / devfreq: tegra: add devfreq driver for Tegra Activity MonitorTomeu Vizoso1-0/+718
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 <[email protected]> and Mikko Perttunen <[email protected]>. Signed-off-by: Tomeu Vizoso <[email protected]> Signed-off-by: MyungJoo Ham <[email protected]>
