Will only work with lower half only 46 trigger consumers. 47 48 To compile this driver as a module, choose M here: the 49 module will be called iio-trig-loop. 50 51config IIO_SYSFS_TRIGGER 52 tristate "SYSFS trigger" 53 depends on SYSFS 54 select IRQ_WORK 55 help 56 Provides support for using SYSFS entries as IIO triggers. 57 If unsure, say N (but it's safe to say "Y"). 58 59 To compile this driver as a module, choose M here: the 60 module will be called iio-trig-sysfs. 61 62endmenu 63
