2012-11-02iio: isl29018: Support suspend and resume.iio-for-3.8bBryan Freed
The driver leaves the device in power-down state anyway, so there is nothing to do on suspend. On resume, we just have to make sure the range and ADC values are updated in the device since it may have been powered down in suspend.

2012-09-08iio: isl29018: Support fractional ALS scaling.iio-for-3.7cBryan Freed
The Industrial IO framework supports scaling ADC values by fractions, but most drivers default to using whole numbers. This change turns on fractional scaling in the isl29018 driver. Signed-off-by: Bryan Freed <bfreed@chromium.org> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

2012-04-29staging: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>

2011-11-26staging:iio:treewide only use shared to decide on interfacesJonathan Cameron
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.

2011-11-26staging:iio: Do not use bitmasks for channel info addressesLars-Peter Clausen
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.

2011-09-09staging:iio:light: V3 fix out of bounds reg_cache[] accessJonathan Cameron
V3 is a straightforward forward port to teh current tree of V2. Simple fix is to just not cache REG_TEST (offset 8). Cache doesn't help REG_TEST anyway since we write all 8 bits exactly once (at resume/init time). Also fix an "off-by-one" allocation of reg_cache[] array size that was in the original code before I touched it.
