Sanjeev Sharma 81816affea iio: remove .owner field for driver using module_platform_driver
This patch removes the .owner field for drivers which use the
platform_driver_register api because this is overriden in
_platform_driver_register.

   the introduction of iio_push_to_buffers_with_timestamp.
 * Drop some unneeded linux/init.h includes
 * Squish a sparse warning in mpl3115 by correctly specifying a be32 variable.
 * A number of cleanups and fixes for sca3000
 * Drop an unneed checks in mxs-lradc, ad7303 and adis16400.
 * Drop a platform_set_drvdata in viperboard after the only use of it was
   removed during a devm conversion.
 * Add a missing device name for ak8975 to comply with the ABI.
 * Put mpu6050 into the IMU menu as it slipped out into the main menu.
 * Fix a typo and some comment formatting in mpu6050.
 * Document at91 ADC clock properties.

Paul Gortmaker 36eb8cc2ce iio: delete non-required instances of include <linux/init.h>
None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>.  Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

Sachin Kamat ae0f29d159 iio: adc: twl6030-gpadc: Remove redundant code
The if check is redundant as the value obtained from
iio_device_register() is already in the required format.
Hence return the function directly.

Oleksandr Kozaruk 1696f36482 iio: twl6030-gpadc: TWL6030, TWL6032 GPADC 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.
