75 * struct devfreq_dev_profile - Devfreq's user device profile
76 * @initial_freq: The operating frequency when devfreq_add_device() is
77 * called.
78 * @polling_ms: The polling interval in ms. 0 disables polling.
79 * @timer: Timer type is either deferrable or delayed timer.
80 * @target: The device should set its operating frequency at
81 * freq or lowest-upper-than-freq value. If freq is
82 * higher than any operable frequency, set maximum.
83 * Before returning, target function should set
84 * freq at the current frequency.
85 * The "flags" parameter's possible values are
86 * explained above with "DEVFREQ_FLAG_*" macros.
87 * @get_dev_status: The device should provide the current performance
88 * status to devfreq. Governors are recommended not to
89 * use this directly. Instead, governors are recommended
90 * to use devfreq_update_stats() along with
91 * devfreq.last_status.
92 * @get_cur_freq: The device should provide the current frequency
93 * at which it is operating.
94 * @exit: An optional callback that is called when devfreq
95 * is removing the devfreq object due to error or
96 * from devfreq_remove_device() call. If the user
97 * has registered devfreq->nb at a notifier-head,
98 * this is the time to unregister it.
99 * @freq_table: Optional list of frequencies to support statistics
100 * and freq_table must be generated in ascending order.
101 * @max_state: The size of freq_table.
102 *
103 * @is_cooling_device: A self-explanatory boolean giving the device a
104 * cooling effect property.
105 * @up_threshold: If the load is over this value, the frequency jumps.
106 * Specify 0 to use the default. Valid value = 0 to 100.
107 * @down_differential: If the load is under upthreshold - downdifferential,
108 * the governor may consider slowing the frequency down.
109 * Specify 0 to use the default. Valid value = 0 to 100.
110 * downdifferential < upthreshold must hold.
