* staging:iio: Streamline API function namingLars-Peter Clausen2012-04-291-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we use two different naming schemes in the IIO API, iio_verb_object and iio_object_verb. E.g iio_device_register and iio_allocate_device. This patches renames instances of the later to the former. The patch also renames allocate to alloc as this seems to be the preferred form throughout the kernel. In particular the following renames are performed by the patch: iio_put_device -> iio_device_put iio_allocate_device -> iio_device_alloc iio_free_device -> iio_device_free iio_get_trigger -> iio_trigger_get iio_put_trigger -> iio_trigger_put iio_allocate_trigger -> iio_trigger_alloc iio_free_trigger -> iio_trigger_free The conversion was done with the following coccinelle patch with manual fixes to comments and documentation. <smpl> @@ @@ -iio_put_device +iio_device_put @@ @@ -iio_allocate_device +iio_device_alloc @@ @@ -iio_free_device +iio_device_free @@ @@ -iio_get_trigger +iio_trigger_get @@ @@ -iio_put_trigger +iio_trigger_put @@ @@ -iio_allocate_trigger +iio_trigger_alloc @@ @@ -iio_free_trigger +iio_trigger_free </smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Acked-by: Jonathan Cameron <jic23@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

* includecheck: delete any duplicate instances of module.hPaul Gortmaker2012-02-281-1/+0
| | | | | | | | | | | | Different tree maintainers picked up independently generated trivial compile fixes based on linux-next testing, resulting in some cases where a file would have got more than one addition of module.h once everything was all merged together. Delete any duplicates so includecheck isn't complaining about anything related to module.h/export.h changes. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
* staging:iio:treewide only use shared to decide on interfacesJonathan Cameron2011-11-261-4/+4
| | | | | | | | | | | | | | | | | | | | | | Internally the fact that say scale is shared across channels is actually of remarkably little interest. Hence lets not store it. Numerous devices have weird combinations of channels sharing scale anyway so it is not as though this was really telling us much. Note however that we do still use the shared sysfs attrs thus massively reducing the number of attrs in complex drivers. Side effect is that certain drivers that were abusing this (mostly my work) needed to do a few more checks on what the channel they are being queried on actually is. This is also helpful for in kernel interfaces where we just want to query the scale and don't care whether it is shared with other channels or not.

* staging:iio: Do not use bitmasks for channel info addressesLars-Peter Clausen2011-11-261-2/+2
| | | | | | | | | | | Currently the iio framework uses bitmasks for the address field of channel info attributes. This is for historical reasons and no longer required since it will only ever query a single info attribute at once. This patch changes the code to use the non-shifted iio_chan_info_enum values for the info attribute address.

* staging:iio:gyro: adis16060 cleanup, move to abi and bug fixes.Jonathan Cameron2011-02-281-76/+49
| | | | | | | | | | | | | | | | | | | | | | | Moved to standard sysfs naming and got rid of direct register writing from userspace. The rx and tx buffers are never used together so just have one and avoid the need to malloc it by using putting it in the state structure and using the ____cacheline_aligned trick. A number of obvious bugs also fixed and correction of register address defines in header which has now been squashed into the driver. I don't have one of these so can't test. This is done off datasheet. Note that the driver had parts that definitely wouldn't work before this patch. Now it 'might' assuming I haven't messed up too badly. I've left fixing the fact that you can only have one of these on a given machine for another day.
