Merge tag 'iio-for-3.7c' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into work-next
Third set of IIO rework and new drivers for the 3.7 cycle.
This set includes:
1) HID sensor drivers. This includes a core elements in the
HID subsystem merged through the IIO tree because we have some
ABI changes outstanding (some in this set) which will effect them.
The HID sensors specification covers an extremely wide range of
sensors so we will probably be seeing lots more elements of this
as the hardware hits the market.
2) Some general abi cleanups to use the utility function
iio_push_to_buffer and to drop the used timestamp parameter
from the same call. For a long time timestamps have taken
the same path as all other channel types into the buffers so
it is good to clean this out.
3) More ADC driver support for Analog Devices parts in the form
of one new driver and some additional supported parts via current
drivers.
4) An increase to the accuracy of the calibration scale for
the isl29018 driver.
So a mixed bag, but all good additions to IIO.
