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 always_on:1; unsigned boot_on:1; unsigned apply_uV:1; };
MEMBERS¶
nameDescriptive 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 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.
