REGULATOR_SYNC_VOLTA(9) API reference REGULATOR_SYNC_VOLTA(9)NAME
regulator_sync_voltage - re-apply last regulator output voltage
SYNOPSIS
int regulator_sync_voltage(struct regulator * regulator);
ARGUMENTS
regulator
regulator source
DESCRIPTION
Re-apply the last configured voltage. This is intended to be used where some external control source the consumer is cooperating with has
caused the configured voltage to change.

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.
map_voltage
Convert a voltage into a selector
set_voltage_sel
Set the voltage for the regulator using the specified selector.
get_voltage
Return the currently configured voltage for the regulator.
get_voltage_sel
Return the currently configured voltage selector for the regulator.
set_current_limit
Configure a limit for a current-limited regulator. The driver should select the current closest to max_uA.
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 stabilise after being enabled, in microseconds.
set_ramp_delay
Set the ramp delay for the regulator. The driver should select ramp delay equal to or less than(closest) ramp_delay.
set_voltage_time_sel
Time taken for the regulator voltage output voltage to stabilise after being set to a new value, in microseconds. The function provides
the from and to voltage selector, the function should return the worst case.
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_bypass
Set the regulator in bypass mode.
get_bypass
Get the regulator bypass mode state.
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.
