The TODO entry - drop global variables, use a proper olpc_dcon_priv struct - is already finished. The driver has no global variables. It uses the private structure 'dcon_priv'. Signed-off-by:

Merge tag 'iio-for-3.12b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: Second round of new drivers, features and cleanups for IIO in the 3.12 cycle. New driver: 1) tmp006 IR thermopile driver. This is an unusual temperature sensor and was taken in to IIO with the knowledge and agreement of a hwmon maintainer. It measures remote temperature using infrared emissions. I guess taking this may mean we have to fight off submissions of devices much more suited to hwmon but such is life and we end up doing this from time to time already. 2) twl6030 adc driver. Cleanups: 1) More devm_* cleanups following on from the introduction of devm_iio_device_alloc. Mostly an heroic effort from Sachin Kamat! 2) Introduce devm_iio_trigger_alloc etc to handle trigger allocation and deallocation in a managed fashion. There aren't as many instances of triggers as devices, but this will allow futher reduction in error patch complexity in some of our most complex drivers making it a very good thing. 3) Trivial removal of unused defines in adjd_s311 4) Drop some write_raw_get_fmt callbacks where they were only returning the default value. 5) Change mxs-lradc realbits to 12. Whilst an 18bit register is used on the device, in its current mode only 12 bits of useful data are returned. For now the packing is unchanged in the buffer and this change mainly effects the input support in the driver.

The GPADC is general purpose ADC found on TWL6030, and TWL6032 PMIC, known also as Phoenix and PhoenixLite. The TWL6030 and TWL6032 have GPADC with 17 and 19 channels respectively. Some channels have current source and are used for measuring voltage drop on resistive load for detecting battery ID resistance, or measuring voltage drop on NTC resistors for external temperature measurements. Some channels measure voltage, (i.e. battery voltage), and have voltage dividers, thus, capable to scale voltage. Some channels are dedicated for measuring die temperature. Some channels are calibrated in 2 points, having offsets from ideal values kept in trim registers. This is used to correct measurements. The differences between GPADC in TWL6030 and TWL6032: - 10 bit vs 12 bit ADC; - 17 vs 19 channels; - channels have different purpose(i.e. battery voltage channel 8 vs channel 18); - trim values are interpreted differently. Based on the driver patched from Balaji TK, Graeme Gregory, Ambresh K, Girish S Ghongdemath. Signed-off-by:

The LRADC virtual channels have an 18 bit field to store the sum of up to 2^5 accumulated samples. The read_raw function however only operates over a single sample (12 bit resolution). In order to use this field for scaling operations, we need it to be the exact resolution value of the LRADC. Besides, the driver was using an 18 bit mask (LRADC_CH_VALUE_MASK) to report touch coordinates to userland. A 12 bit mask should be used instead or else the touch libraries will expect a coordinates range between 0 and 0x3ffff (18 bits), instead of between 0 and 0xfff (12 bits). Signed-off-by:

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 Signed-off-by:

Macro get_unused_fd() is used to allocate a file descriptor with default flags. Those default flags (0) can be "unsafe": O_CLOEXEC must be used by default to not leak file descriptor across exec(). Instead of macro get_unused_fd(), functions anon_inode_getfd() or get_unused_fd_flags() should be used with flags given by userspace. If not possible, flags should be set to O_CLOEXEC to provide userspace with a default safe behavor. In a further patch, get_unused_fd() will be removed so that new code start using anon_inode_getfd() or get_unused_fd_flags() with correct flags. This patch replaces calls to get_unused_fd() with call to get_unused_fd_flags(O_CLOEXEC) following advice from Erik Gilling. Signed-off-by:
