staging:iio: header reorganization
Issue brought up by Lars-Peter Clausen. This is a varient of what
he suggested.
io/iio.h for driver stuff (has to include types.h)
Sub files for the bits drivers may or may not use
iio/sysfs.h
iio/buffer.h (contents of current buffer_generic.h)
(obviously anything offering events will need events.h as well)
iio/types.h for the enums that matter to both
iio_chan_type, iio_modifier
iio/events.h for the event code stuff
IIO_EVENT_CODE and friends. + everything in chrdev.h So this
is the stuff that userspace cares about.
Also include iio_event_type, iio_event_direction
Thus iio drivers include iio.h + as required
events.h
sysfs.h
buffer.h
in kernel users (once that interface is merged) will need inkern.h
which will pull in types.h
Userspace will need just events.h (which pulls in types.h) to get
everything they need to know about. Buffer userspace access doesn't
currently need any core defines. All information about the data
format is passed through sysfs.
