regulator_has_full_constraints(9) [centos man page]

REGULATOR_HAS_FULL_C(9) 					   API reference					   REGULATOR_HAS_FULL_C(9)

NAME

       regulator_has_full_constraints - the system has fully specified constraints

SYNOPSIS

       void regulator_has_full_constraints(void);

ARGUMENTS

       void
	   no arguments

DESCRIPTION

       Calling this function will cause the regulator API to disable all regulators which have a zero use count and don't have an always_on
       constraint in a late_initcall.

       The intention is that this will become the default behaviour in a future kernel release so users are encouraged to use this facility now.

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.
