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.

set_input_current_limit

Configure an input limit.

set_over_current_protection

Support capability of automatically shutting down when detecting an over current event.

set_active_discharge

Set active discharge enable/disable of regulators.

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

Time taken for the regulator voltage output voltage to stabilise after being set to a new value, in microseconds. The function receives the from and to voltage as input, it should return the worst case.

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 receives the from and to voltage selector as input, it should return the worst case.

set_soft_start

Enable soft start for the regulator.

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_load

Set the load for the regulator.

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.

set_pull_down

Configure the regulator to pull down when the regulator is disabled.
