* staging:iio:adis16400_ring: Pass IIO device directlyLars-Peter Clausen2012-05-141-7/+5
| | | | | | | | | | | When calling adis16350_spi_read_all and adis16400_spi_read_burst we pass the device struct of embedded in the IIO device only to look up the IIO device from the device struct again right away. This patch changes the code to pass the IIO device directly.

| | | | | | | | | | | | | | | | | channels. This is as light as possible on changes to current drivers. Some drivers make assumptions that their masks fit in a single long. Given they were previously working this is clearly valid if not tidy. The max1363 is an example where there should be no such assumptions.

* staging:iio:various move default scan mask setting after ring register or removeJonathan Cameron2011-09-061-3/+0
| | | | | | | | | | | | | | | | | The scan mask will be dynamically assigned in register, so don't use it before that. In adis16260 I've moved it as I know this driver has userspace code. Same for sca3000 where it is cost free due to hardware buffer. Can do that for the others, but in theory userspace code should always have been checking these and setting them appropriately anyway!

* staging:iio: rationalization of different buffer implementation hooks.Jonathan Cameron2011-05-191-6/+10
| | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | Next patch will remove the current adis16350 driver. These should have been merged a long time ago, but there we are. V3: rebase fixup + add missing extend_name for supply on adis16350 V2: Move to single IIO_CHAN macro + use the new extend_name to make the naming of the temperature sensors contain x, y, z rather than messing with modifiers.
