2010-07-22staging: iio: Add a bits per element element to ring_generic allowing a general ring_sw_preenable_function.Barry Song1-0/+2

2010-07-22staging: iio: Fix scan_element naming issueJonathan Cameron1-3/+7
The addition of a number to the scan_element names caused an issue in drivers that used either #define or an enum to provide the number. Before this fix names like ADIS16350_ACCEL_X_accel_x_en occur rather than 5_accel_x_en. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2010-05-11staging: IIO: Fix uses of spinlocks prior to init in ring implementationsJonathan Cameron1-5/+3
Some confusion was caused by the ___iio_init_ring_buffer and equivalent in ring_sw handling both init of spin locks etc and allocation and of the actual buffer. This resulted in ring->use_lock being held before it was initialized and actually during the initialization. Some of the recent cleanups in the spin lock code seem to have triggered the bug actually causing traceable crashes. The following patch should fix this but hasn't been extensively tested as of yet and there may well be some side effects I haven't thought of. Just wanted to get this out there before anyone else runs into it! Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2010-03-03Staging: make drivers use spin_lock_init()Sven-Thorsten Dietrich1-2/+1

2009-12-11Staging: iio: lots of doc fixesRandy Dunlap1-28/+45
Fix iio header files kernel-doc notation errors, spelling, typos, indentation, grammar, etc. It would also be good if these function names were spelled correctly, but I didn't change them: iio_push_or_escallate_ring_event() iio_trigger_dettach_poll_func() Signed-off-by: Randy Dunlap <randy.dunlap@oracle.com> Acked-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-09-15Staging: IIO: Add generic ring buffer support to the IIO coreJonathan Cameron1-0/+283
This provides a unified interface for hardware and software ring buffers. Changes since V2: * Moved to a more consistent structure. Now the ring buffer has an associated struct device which is a child of the relevant iio_dev. This in turn has two children, one for the event interface and one for the access interface. These two interfaces are now managed via cdev structures. * Numerous minor cleanups Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
