MEMBERS

ops
[DRIVER] operations structure

id

[INTERN] unique id number

name

[DRIVER] unique name

dev

[DRIVER] associated device (if relevant)

list

[INTERN] used in maintenance of global trigger list

alloc_list

[DRIVER] used for driver specific trigger list

use_count

use count for the trigger

subirq_chip

[INTERN] associate 'virtual' irq chip.

subirq_base

[INTERN] base number for irqs provided by trigger.

subirqs[CONFIG_IIO_CONSUMERS_PER_TRIGGER]

[INTERN] information about the 'child' irqs.

pool[BITS_TO_LONGS(CONFIG_IIO_CONSUMERS_PER_TRIGGER)]

[INTERN] bitmap of irqs currently in use.

pool_lock

[INTERN] protection of the irq pool.
