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.
