0244ad004a Remove GENERIC_HARDIRQ config option
After the last architecture switched to generic hard irqs the config
options HAVE_GENERIC_HARDIRQS & GENERIC_HARDIRQS and the related code
for !CONFIG_GENERIC_HARDIRQS can be removed.

e5a6394218 iio: Add tmp006 IR temperature sensor
the TI TMP006 is a non-contact temperature sensor with I2C interface;
it measures the surface temperature of a distance object using a
thermopile to absorb IR energy emitted from the object

the sensor has two channels: IR sensor voltage (16-bit) and reference
temperature of the chip (14-bit); datasheet is here:
http://www.ti.com/lit/ds/symlink/tmp006.pdf

v2 (thanks to Grygorii Strashko, Lars-Peter Clausen, Jonathan Cameron
for review comments):
* power down device on driver remove
* use sign_extend32()
* style cleanup
* add comments what channel raw LSBs mean
* spelling of thermopile

6a48a9d5d7 Revert "iio: add configuration option for debug support"
This reverts commit 98a5e9e99d.

IIO, like the rest of the kernel, should rely on dynamic debugging, not
have a special config option for it.  That way, no user has to rebuild
their kernel to have debug messages, which is a good thing, let's not
revert back to the bad old days of the 2000's.

This simple driver is rather useful. No issues about its interface

dbdc025bb2 staging:iio: Move DAC drivers out of staging
The IIO DAC drivers are in a reasonably good shape. They all make use of channel
spec and non of them provides non-documented sysfs attributes. Code style should
be OK as well, both checkpatch and coccicheck only report trivial issues.

So lets move the whole folder out of staging.

9c8ea1b29b iio: add LM3533 ambient-light-sensor driver
Add sub-driver for the ambient-light-sensor interface on National
Semiconductor / TI LM3533 lighting power chips.

The sensor interface can be used to control the LEDs and backlights of
the chip through defining five light zones and three sets of
corresponding output-current values.

The driver provides raw and mean adc readings along with the current
light zone through sysfs. A threshold event can be generated on zone
changes. The ALS-control output values can be set per zone for the three
current output channels.
