......@@ -228,3 +228,22 @@ is the corresponding frequency table helper for the ->target
stage. Just pass the values to this function, and the unsigned int
index returns the number of the frequency table entry which contains
the frequency the CPU shall be set to.
The following macros can be used as iterators over cpufreq_frequency_table:
cpufreq_for_each_entry(pos, table) - iterates over all entries of frequency
table.
cpufreq-for_each_valid_entry(pos, table) - iterates over all entries,
excluding CPUFREQ_ENTRY_INVALID frequencies.
Use arguments "pos" - a cpufreq_frequency_table * as a loop cursor and
"table" - the cpufreq_frequency_table * you want to iterate over.
For example:
struct cpufreq_frequency_table *pos, *driver_freq_table;
cpufreq_for_each_entry(pos, driver_freq_table) {
/* Do something with pos */
pos->frequency = ...
}

Say yes here to add support for Maxim Semiconductor MAX14577.
This is a Micro-USB IC with Charger controls on chip.
Say yes here to add support for Maxim Semiconductor MAX14577 and
MAX77836 Micro-USB ICs with battery charger.
This driver provides common support for accessing the device;
additional drivers must be enabled in order to use the functionality
of the device.
