3. 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.

4. DESCRIPTION

This struct describes regulator and board/machine specific constraints.
