After UAPI header file split [1] all user-kernel interfaces were
placed under include/uapi/.
This patch moves IIO user specific API from:
* include/linux/iio/events.h => include/uapi/linux/iio/events.h
* include/linux/iio/types.h => include/uapi/linux/iio/types.h
Now there is no need for nasty tricks to compile userspace programs
(e.g iio_event_monitor). Just installing the kernel headers with
make headers_install command does the job.

Thanks for taking care of this, this is something that should have done a
while ago.
Hi Lars,
Thanks for the feedback!

I think everything in this file below is not part of the ABI and should not
be exported to userspace.
I agree about iio_event_info and IIO_VAL_* constants.
-
-enum iio_event_info {
- IIO_EV_INFO_ENABLE,
- IIO_EV_INFO_VALUE,
- IIO_EV_INFO_HYSTERESIS,
- IIO_EV_INFO_PERIOD,
-};
-
-enum iio_event_direction {
- IIO_EV_DIR_EITHER,
- IIO_EV_DIR_RISING,
- IIO_EV_DIR_FALLING,
- IIO_EV_DIR_NONE,
-};
iio_event_direction is exported to userspace via IIO_EVENT_CODE and
I think it belongs to this file.
Right.

-#define IIO_VAL_INT 1
-#define IIO_VAL_INT_PLUS_MICRO 2
-#define IIO_VAL_INT_PLUS_NANO 3
-#define IIO_VAL_INT_PLUS_MICRO_DB 4
-#define IIO_VAL_INT_MULTIPLE 5
-#define IIO_VAL_FRACTIONAL 10
-#define IIO_VAL_FRACTIONAL_LOG2 11

I will send v2 in few hours, hopefully I'll get more feedback meanwhile.
Do you thing should I remove the RFC tag?
Patch looks good to me.
