STRUCT 
REGULATION_CO(9) API reference STRUCT REGULATION_CO(9) NAME
struct_regulation_constraints - regulator operating constraints. SYNOPSIS
struct regulation_constraints { const char * name; int min_uV; int max_uV; int uV_offset; int min_uA; int max_uA; unsigned int valid_modes_mask; unsigned int valid_ops_mask; int input_uV; struct regulator_state state_disk; struct regulator_state state_mem; struct regulator_state state_standby; suspend_state_t initial_state; unsigned int initial_mode; unsigned int ramp_delay; unsigned always_on:1; unsigned boot_on:1; unsigned apply_uV:1; }; 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. AUTHORS

STRUCT 
REGULATOR_OPS(9) API reference STRUCT REGULATOR_OPS(9) NAME
struct_regulator_ops - regulator operations. SYNOPSIS
struct regulator_ops { int (* list_voltage) (struct regulator_dev *, unsigned selector); int (* set_voltage) (struct regulator_dev *, int min_uV, int max_uV); int (* get_voltage) (struct regulator_dev *); int (* set_current_limit) (struct regulator_dev *,int min_uA, int max_uA); int (* get_current_limit) (struct regulator_dev *); int (* enable) (struct regulator_dev *); int (* disable) (struct regulator_dev *); int (* is_enabled) (struct regulator_dev *); int (* set_mode) (struct regulator_dev *, unsigned int mode); unsigned int (* get_mode) (struct regulator_dev *); int (* enable_time) (struct regulator_dev *); int (* get_status) (struct regulator_dev *); unsigned int (* get_optimum_mode) (struct regulator_dev *, int input_uV,int output_uV, int load_uA); int (* set_suspend_voltage) (struct regulator_dev *, int uV); int (* set_suspend_enable) (struct regulator_dev *); int (* set_suspend_disable) (struct regulator_dev *); int (* set_suspend_mode) (struct regulator_dev *, unsigned int mode); }; 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.
