2013-10-24iio: dac: ad5755: Remove redundant codeSachin Kamat1-7/+1
The if check is redundant as the value obtained from iio_device_register() is already in the required format. Error messages are already printed by iio_device_register(); hence not needed. Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

2013-09-29Merge tag 'iio-for-3.13b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-nextGreg Kroah-Hartman2-1/+7
Jonathan writes: Second set of new functionality for IIO in the 3.13 cycle - with bug fixes for first set. This is a small, mainly to get a couple of compile bug related fixes into the tree ASAP. New device support: 1) Add ad5446 dac support to the ad5641 driver. New functionality and cleanups: 1) Optional power supply regulators for the st pressure sensors drivers using the new optional regulator interface. 2) Bit of tidying up of naming in the sysfs trigger. Bug fixes from the previous series: 1) Missing select IIO_BUFFER for ti_am335x_adc 2) Drop a bonus bracket in iio-trig-bfin-timmer

Introduce an enum to specify whether the attribute is separate or shared. Factor out the bitmap handling for loop into a separate function.

2013-08-03iio: Add a comment to about alphabetical order to Kconfigs and MakefilesLars-Peter Clausen2-18/+21
Keeping Makefile and Kconfig entries in alphabetical order usually works better than just appending new entries at the end, since it reduces the amount of conflicts. This patch adds a comment to the IIO Kconfig and Makefile files to document that the entries should be kept in alphabetical order. Also reorder those entries which weren't in alphabetical order yet.

Thus don't allow the drivers to be compiled as built-in when CONFIG_I2C=m. The real fix though is to break the driver apart into a SPI part, an I2C part and a common part. But that's something for 3.11 while this is something for 3.10/stable.

2013-03-25Merge tag 'iio-for-3.10a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-nextGreg Kroah-Hartman14-44/+44
Jonathan writes: First set of IIO new drivers and cleanup for the 3.10 cycle. New stuff 1) Add OF support for specifying mappings between iio devices and their in kernel consumers. 2) Driver for AD7923 (extra functionality and support for ad7904, ad7914 and ad7924 added later in series) 3) Driver for Exynos adc (dt suppor for phy added later in series). 4) Make iio_push_event save IRQ context - necessary if it is to be used within an interrupt handler. Users of this functionality to follow. 5) For iio use the device tree node name to provide the hwmon name attribute if available. Removal and moves out of staging 1) Drop the adt7410 driver from IIO now that there is a hmwon driver with equivalent support. This device is very much targeted at hardware monitoring so hwmon is a more appropriate host for the driver. 2) Move iio_hwmon driver to drivers/hwmon. Cleanups 1) Minor cleanup in ST common library. 2) Large set of patches to break the info_mask element which previously used odd and even bits to specify if a channel attribute was either shared across similar channels or specific to only one. Now we have two bitmaps, one for those parameters that are specific to this channel and one for those shared by all channels with the same type as this one. This has no effect on the userspace abi. It simplifies the core code and provides more space for new channel parameters. It has been on the todo list for a long time! Conflicts: drivers/iio/dac/ad5064.c
