2013-01-26staging:iio:adis16080: Move out of stagingLars-Peter Clausen
The driver is rather simple and in a good shape. It follows the IIO ABI and the standard codechecker tools do not report any issues, so move it out of staging. While moving it also remove one outdated 'fixme' comment. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

2013-01-26staging:iio:adis16080: Remove unnecessary lockLars-Peter Clausen
All sections in which the transfer buffer is accessed are already protected by the IIO device's mlock. So we do not need the extra mutex protecting the buffer. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2013-01-26staging:iio:adis16080: be16 cleanupsLars-Peter Clausen
The sample buffer contains big endian 16bit words. So use the be16 datatype for the buffer and use the proper helper functions for endianness conversion instead of openconding it. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2013-01-26staging:iio:adis16080: Cleanup SPI transferLars-Peter Clausen
During sampling the driver currently does a spi_read followed by a spi_write. This is not a problem per se, since CS needs to be deasserted between the two transfers. So even if another device claims the bus between the two transfers we should still get a result. But the code is actually spread out over multiple functions. E.g. the spi_read happens in one function the spi_write in another, this makes the code harder to follow. This patch re-factors the code to just use a single spi transaction to do both the read and the write transfer.

2013-01-26staging:iio:adis16080: Add device id table entry for the adis16100Lars-Peter Clausen
The adis16100 is very similar to the adis16080. The driver description already states that the driver supports the adis16100 as-well. But so far the there is no device id table for the adis16100 and the drivers does not bind to a device named adis16100.

2013-01-09staging:iio:adis16080: Perform sign extensionLars-Peter Clausen
The adis16080 reports sample values in twos complement. So we need to perform a sign extension on the result, otherwise negative values will be reported incorrectly as large positive values. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

2012-04-30staging:iio: Streamline API function namingLars-Peter Clausen
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>

2011-11-27staging:iio: Add missing MODULE_DEVICE_TABLE and MODULE_ALIASLars-Peter Clausen
Quite a few iio drivers provide no MODULE_DEVICE_TABLE or MODULE_ALIAS or only provide a MODULE_ALIAS while they have support for multiple device ids. This prevents auto module loading from working correctly. This patch fixes it by adding the missing MODULE_DEVICE_TABLEs and MODULE_ALIAS'.

2011-03-01staging:iio:gyro: adis16080 cleanup, move to abi and bug fixes.Jonathan Cameron
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. Couple of obvious bug fixes whilst I was here. I don't have one of these so can't test. This is done off datasheet. Note that as with the adis16060 driver there are parts that definitely wouldn't work before this patch. Now it 'might' assuming I haven't messed up too badly.
