134 frequency table helpers might be helpful. See the section 2 for more information
146 See section 2 for details on frequency table helpers.
148 You need to make sure that at least one valid frequency (or operating
156 Most cpufreq drivers or even most cpu frequency scaling algorithms
157 only allow the CPU frequency to be set to predefined fixed values. For
161 Some cpufreq capable processors switch the frequency between certain
169 and ``unsigned int`` index (into the exposed frequency table).
171 The CPUfreq driver must set the new frequency when called here. The
172 actual frequency must be determined by freq_table[index].frequency.
174 It should always restore to earlier frequency (i.e. policy->restore_freq) in
175 case of errors, even if we switched to intermediate frequency earlier.
182 The CPUfreq driver must set the new frequency when called here. The
183 actual frequency must be determined using the following rules:
192 Here again the frequency table helper might assist you - see section 2

223 get_intermediate should return a stable intermediate frequency platform wants to
224 switch to, and target_intermediate() should set CPU to that frequency, before
225 jumping to the frequency corresponding to 'index'. Core will take care of

241 frequencies, a "frequency table" with some functions might assist in
242 some work of the processor driver. Such a "frequency table" consists of
244 values in "driver_data", the corresponding frequency in "frequency" and

259 cpufreq_frequency_table_target() is the corresponding frequency table
261 and this function returns the of the frequency table entry which
262 contains the frequency the CPU shall be set to.
