Present\ncode continues monitoring unless device is removed from\ndevfreq core.\n\nThis patch introduces following design changes,\n\n - use per device work instead of global work to monitor device\n   load. This enables suspend/resume of device devfreq and\n   reduces monitoring code complexity.\n - decouple delayed work based load monitoring logic from core\n   by introducing helpers functions to be used by governors. This\n   provides flexibility for governors either to use delayed work\n   based monitoring functions or to implement their own mechanism.\n - devfreq core interacts with governors via events to perform\n   specific actions.

      "message": "PM: Introduce devfreq: generic DVFS framework with device-specific OPPs\n\nWith OPPs, a device may have multiple operable frequency and voltage\nsets. However, there can be multiple possible operable sets and a system\nwill need to choose one from them. In order to reduce the power\nconsumption (by reducing frequency and voltage) without affecting the\nperformance too much, a Dynamic Voltage and Frequency Scaling (DVFS)\nscheme may be used.\n\nThis patch introduces the DVFS capability to non-CPU devices with OPPs.\nDVFS is a techique whereby the frequency and supplied voltage of a\ndevice is adjusted on-the-fly. DVFS usually sets the frequency as low\nas possible with given conditions (such as QoS assurance) and adjusts\nvoltage according to the chosen frequency in order to reduce power\nconsumption and heat dissipation.\n\nThe generic DVFS for devices, devfreq, may appear quite similar with\n/drivers/cpufreq.  However, cpufreq does not allow to have multiple\ndevices registered and is not suitable to have multiple heterogenous\ndevices with different (but simple) governors.\n\nNormally, DVFS mechanism controls frequency based on the demand for\nthe device, and then, chooses voltage based on the chosen frequency.\ndevfreq also controls the frequency based on the governor\u0027s frequency\nrecommendation and let OPP pick up the pair of frequency and voltage\nbased on the recommended frequency. Then, the chosen OPP is passed to\ndevice driver\u0027s \"target\" callback.\n\nWhen PM QoS is going to be used with the devfreq device, the device\ndriver should enable OPPs that are appropriate with the current PM QoS\nrequests. In order to do so, the device driver may call opp_enable and\nopp_disable at the notifier callback of PM QoS so that PM QoS\u0027s\nupdate_target() call enables the appropriate OPPs. Note that at least\none of OPPs should be enabled at any time; be careful when there is a\ntransition.\n\nSigned-off-by: MyungJoo Ham \u003cmyungjoo.ham@samsung.com\u003e\nSigned-off-by: Kyungmin Park \u003ckyungmin.park@samsung.com\u003e\nReviewed-by: Mike Turquette \u003cmturquette@ti.com\u003e\nAcked-by: Kevin Hilman \u003ckhilman@ti.com\u003e\nSigned-off-by: Rafael J.
