Members

name

Identifying name for the regulator.

supply_name

Identifying the regulator supply

of_match

Name used to identify regulator in DT.

regulators_node

Name of node containing regulator definitions in DT.

of_parse_cb

Optional callback called only if of_match is present. Will be called for each regulator parsed from DT, during init_data parsing. The regulator_config passed as argument to the callback will be a copy of config passed to regulator_register, valid only for this particular call. Callback may freely change the config but it cannot store it for later usage. Callback should return 0 on success or negative ERRNO indicating failure.

id

Numerical identifier for the regulator.

continuous_voltage_range

Indicates if the regulator can set any voltage within constrains range.

n_voltages

Number of selectors available for ops.list_voltage.

ops

Regulator operations table.

irq

Interrupt number for the regulator.

type

Indicates if the regulator is a voltage or current regulator.

owner

Module providing the regulator, used for refcounting.

min_uV

Voltage given by the lowest selector (if linear mapping)

uV_step

Voltage increase with each selector (if linear mapping)

linear_min_sel

Minimal selector for starting linear mapping

fixed_uV

Fixed voltage of rails.

ramp_delay

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

min_dropout_uV

The minimum dropout voltage this regulator can handle

linear_ranges

A constant table of possible voltage ranges.

n_linear_ranges

Number of entries in the linear_ranges table.

volt_table

Voltage mapping table (if table based mapping)

vsel_reg

Register for selector when using regulator_regmap_X_voltage_

vsel_mask

Mask for register bitfield used for selector

csel_reg

Register for TPS65218 LS3 current regulator

csel_mask

Mask for TPS65218 LS3 current regulator

apply_reg

Register for initiate voltage change on the output when using regulator_set_voltage_sel_regmap

apply_bit

Register bitfield used for initiate voltage change on the output when using regulator_set_voltage_sel_regmap

enable_reg

Register for control when using regmap enable/disable ops

enable_mask

Mask for control when using regmap enable/disable ops

enable_val

Enabling value for control when using regmap enable/disable ops

disable_val

Disabling value for control when using regmap enable/disable ops

enable_is_inverted

A flag to indicate set enable_mask bits to disable when using regulator_enable_regmap and friends APIs.

bypass_reg

Register for control when using regmap set_bypass

bypass_mask

Mask for control when using regmap set_bypass

bypass_val_on

Enabling value for control when using regmap set_bypass

bypass_val_off

Disabling value for control when using regmap set_bypass

active_discharge_on

Disabling value for control when using regmap set_active_discharge

active_discharge_off

Enabling value for control when using regmap set_active_discharge

active_discharge_mask

Mask for control when using regmap set_active_discharge

active_discharge_reg

Register for control when using regmap set_active_discharge

enable_time

Time taken for initial enable of regulator (in uS).

off_on_delay

guard time (in uS), before re-enabling a regulator

of_map_mode

Maps a hardware mode defined in a DeviceTree to a standard mode

Description

Each regulator registered with the core is described with a structure of this type and a struct regulator_config. This structure contains the non-varying parts of the regulator description.
