Merge tag 'iio-for-3.10a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

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
