git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: Second set of new drivers, functionality and cleanups for IIO in the 4.4 cycle. Core stuff * adjust resistance documentation to allow for output devices. New device support: * bmc150 - split the i2c driver up into a core and i2c_regmap part including regmap conversion. - add spi support. * mcp4531 digitial potentiometer driver. * Measurement Specialties set of drivers with a core library module providing common functionality. Note that the htu21 has a driver in hwmon, but the view from that side was that, given the range of devices the same silicon turns up in are not all typical hwmon material, that driver would be deprecated in favour of this new support. - ms8607 temperature, pressure and humidty sensor - ms5637 temperature and pressure sensor - htu21 temperature and humidity sensor - tsys02d temperature sensor - tsys01 temperature sensor Cleanups * tree wide. - squish cases where irq 0 is still considered valid. * apds9960 - sparse endian warning cleanups by making endianness explicit. * ad5504 - leave group naming to the core. * ad7746 - cleanup comment style. - drop an unnecessary bit of dev_info - add some appropriate uses of the BIT macro. * ad799x - leave group naming to the core. * hdc100x - introduced this cycle,. - fix a wrong offset value. * lidar - add missing MODULE_DEVICE_TABLE for dt. * max1363 - leave sysfs group naming to the core. * m62332 got the Harmut treatment and as ever he found a 'few' bits the rest of us had missed! - Share scale and offset attributes across channels. - Shutdown the device on driver remove - Use ARRAY_SIZE rather than a hard coded count for channels. - Return more directly in the write_raw callback dropping a local variable along the way. - a few style issues - move to reading the regulator voltage for each use allowing for dynamic regulators. This is a common feature across drivers so we might end up with more fixes throughout the tree for this. * mlx96014 - introduced this cycle. - fixed up a spot of error handling. * vz89x - introduced this cycle. - work around a hardware quirk.

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.
