REGULATOR_LIST_VOLTA(9) API reference REGULATOR_LIST_VOLTA(9)NAME
regulator_list_voltage - enumerate supported voltages
SYNOPSIS
int regulator_list_voltage(struct regulator * regulator, unsigned selector);
ARGUMENTS
regulator
regulator source
selector
identify voltage to list
CONTEXT
can sleep
DESCRIPTION
Returns a voltage that can be passed to regulator_set_voltage(), zero if this selector code can't be used on this system, or a negative
errno.

MEMBERS
list_voltage
Return one of the supported voltages, in microvolts; zero if the selector indicates a voltage that is unusable on this system; or
negative errno. Selectors range from zero to one less than regulator_desc.n_voltages. Voltages may be reported in any order.
set_voltage
Set the voltage for the regulator within the range specified. The driver should select the voltage closest to min_uV.
get_voltage
Return the currently configured voltage for the regulator.
set_current_limit
Configure a limit for a current-limited regulator.
get_current_limit
Get the configured limit for a current-limited regulator.
enable
Configure the regulator as enabled.
disable
Configure the regulator as disabled.
is_enabled
Return 1 if the regulator is enabled, 0 if not. May also return negative errno.
set_mode
Set the configured operating mode for the regulator.
get_mode
Get the configured operating mode for the regulator.
enable_time
Time taken for the regulator voltage output voltage to stabalise after being enabled, in microseconds.
get_status
Return actual (not as-configured) status of regulator, as a REGULATOR_STATUS value (or negative errno)
get_optimum_mode
Get the most efficient operating mode for the regulator when running with the specified parameters.
set_suspend_voltage
Set the voltage for the regulator when the system is suspended.
set_suspend_enable
Mark the regulator as enabled when the system is suspended.
set_suspend_disable
Mark the regulator as disabled when the system is suspended.
set_suspend_mode
Set the operating mode for the regulator when the system is suspended.
DESCRIPTION
This struct describes regulator operations which can be implemented by regulator chip drivers.
