| | | | | | | | | | Use private data space from iio_allocate_device. Drop dev_data in favor of iio_priv(). Fix indention issues from previous patches.

* staging:iio: rationalization of different buffer implementation hooks.Jonathan Cameron2011-05-201-7/+11
| | | | | | | | | | | | | 1) move a generic helper function out of ring_sw. It applies to other buffers as well. 2) Get rid of a lot of left over function definitions. 3) Move all the access functions into static structures. 4) Introduce and use a static structure for the setup functions, preenable etc. Some driver conversions thanks to Michael Hennerich (pulled out of patches that would otherwise sit after this).

* staging:iio:trigger handle name attr in core, remove old alloc and register ↵Jonathan Cameron2011-05-201-15/+4Star
| | | | | | | | | | | | | | | | | | | any control_attrs via struct device As the majority of triggers don't actually have any other control_attrs lets use the fact that struct device has a groups element when we do need to have these attributes registered. A vargs function is used to cut down on lots of building strings in every single driver just in order to pass them into the allocate. Also iio_allocate_trigger_named -> iio_allocate_trigger as there is no unamed version any more, so that is now just confusing. Blackfin tested and fixed by Michael Hennerich.

* staging:iio:meter:ade7758: Use iio channel spec and miscellaneous other changes.Michael Hennerich2011-05-203-212/+258
| | | | | | | | | | | | | | | | | | | Use iio channel spec for the ring buffer channels. Add/update file comment/license headers. Use available_scan_masks to prevent that multiple channels are enabled. Remove wavefrom type attributes. (no handled directly by the scan_elements) Use SPI_MODE_1. Move ade7758_initial_setup() before ade7758_probe_trigger() to ensure the ADE7758 interrupt is disabled when the host interrupt get's enabled. Add spi_device_id. Update ring buffer setup. Some backporting needed to ensure driver builds all the way through core changes.

| | | | | | | | | | | | This was only used for triggering and hence should never have been done this way in the first place. Needs to go prior to cleaning out some of the registration functions.

| | | | | | | | | | | | | Suggested by Arnd Bergmann. Note this will break ALL drivers that are out of mainline.
