REGULATOR_ENABLE(9)						   API reference					       REGULATOR_ENABLE(9)

NAME

       regulator_enable - enable regulator output

SYNOPSIS

       int regulator_enable(struct regulator * regulator);

ARGUMENTS

       regulator
	   regulator source

DESCRIPTION

       Request that the regulator be enabled with the regulator output at the predefined voltage or current value. Calls to regulator_enable must
       be balanced with calls to regulator_disable.

NOTE

       the output value can be set by other drivers, boot loader or may be hardwired in the regulator.

MEMBERS

       name
	   Descriptive name for the constraints, used for display purposes.

       min_uV
	   Smallest voltage consumers may set.

       max_uV
	   Largest voltage consumers may set.

       uV_offset
	   Offset applied to voltages from consumer to compensate for voltage drops.

       min_uA
	   Smallest current consumers may set.

       max_uA
	   Largest current consumers may set.

       valid_modes_mask
	   Mask of modes which may be configured by consumers.

       valid_ops_mask
	   Operations which may be performed by consumers.

       input_uV
	   Input voltage for regulator when supplied by another regulator.

       state_disk
	   State for regulator when system is suspended in disk mode.

       state_mem
	   State for regulator when system is suspended in mem mode.

       state_standby
	   State for regulator when system is suspended in standby mode.

       initial_state
	   Suspend state to set by default.

       initial_mode
	   Mode to set at startup.

       ramp_delay
	   Time to settle down after voltage change (unit: uV/us)

       always_on
	   Set if the regulator should never be disabled.

       boot_on
	   Set if the regulator is enabled when the system is initially started. If the regulator is not enabled by the hardware or bootloader
	   then it will be enabled when the constraints are applied.

       apply_uV
	   Apply the voltage constraint when initialising.

DESCRIPTION

       This struct describes regulator and board/machine specific constraints.
