2013-09-29Merge tag 'iio-for-3.13b' of ↵Greg Kroah-Hartman
git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next 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

2013-09-15iio: refactor info mask and ext_info attribute creation.Jonathan Cameron
Introduce an enum to specify whether the attribute is separate or shared. Factor out the bitmap handling for loop into a separate function. Tidy up error handling and add a NULL assignment to squish a false positive warning from GCC. Change ext_info shared type from boolean to enum and update in all drivers.
