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.
min_uA
Smallest consumers 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.
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.
