29
31 name
32 Descriptive name for the constraints, used for display purposes.
33
34 min_uV
35 Smallest voltage consumers may set.
36
37 max_uV
38 Largest voltage consumers may set.
39
40 uV_offset
41 Offset applied to voltages from consumer to compensate for voltage
42 drops.
43
44 min_uA
45 Smallest current consumers may set.
46
47 max_uA
48 Largest current consumers may set.
49
50 valid_modes_mask
51 Mask of modes which may be configured by consumers.
52
53 valid_ops_mask
54 Operations which may be performed by consumers.
55
56 input_uV
57 Input voltage for regulator when supplied by another regulator.
58
59 state_disk
60 State for regulator when system is suspended in disk mode.
61
62 state_mem
63 State for regulator when system is suspended in mem mode.
64
65 state_standby
66 State for regulator when system is suspended in standby mode.
67
68 initial_state
69 Suspend state to set by default.
70
71 initial_mode
72 Mode to set at startup.
73
74 ramp_delay
75 Time to settle down after voltage change (unit: uV/us)
76
77 always_on
78 Set if the regulator should never be disabled.
79
80 boot_on
81 Set if the regulator is enabled when the system is initially
82 started. If the regulator is not enabled by the hardware or
83 bootloader then it will be enabled when the constraints are
84 applied.
85
86 apply_uV
87 Apply the voltage constraint when initialising.
88
90 This struct describes regulator and board/machine specific constraints.
