REGULATOR_SET_VOLTAG(9) 					   API reference					   REGULATOR_SET_VOLTAG(9)

NAME

       regulator_set_voltage_sel_regmap - standard set_voltage_sel for regmap users

SYNOPSIS

       int regulator_set_voltage_sel_regmap(struct regulator_dev * rdev, unsigned sel);

ARGUMENTS

       rdev
	   regulator to operate on

       sel
	   Selector to set

DESCRIPTION

       Regulators that use regmap for their register I/O can set the vsel_reg and vsel_mask fields in their descriptor and then use this as their
       set_voltage_vsel operation, saving some code.

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.
