iio: inv_mpu6050: Fix indio_dev->trig assignment

2014-08-25T20:49:11+00:00

This can result in wrong reference count for trigger device, call
iio_trigger_get to increment reference.
Refer to http://www.spinics.net/lists/linux-iio/msg13669.html for discussion
with Jonathan.

iio: imu: adis16480 switch sampling frequency attr to core support

2014-07-07T09:00:59+00:00

By using the info_mask_shared_by_all element of the channel spec, access
to the sampling frequency becomes available to in kernel users of the
driver.  It also shortens and simplifies the code.

iio:imu:mpu6050: Fixed segfault in Invensens MPU driver due to null dereference

2014-04-26T10:14:51+00:00

The driver segfaults when the kernel boots with device tree as the
platform data is then not present and the pointer is deferenced without
checking it is not null.  This patch introduces such a check avoiding the
crash.

iio: imu: inv_mpu6050: Add compatibity with MPU6500

2014-03-29T10:45:09+00:00

Adding MPU6500 in target list for this driver.

Description:
Source
Document: MPU-6500 Register Map and Descriptions Revision 2.1
Section 3: Register Map

This section describes difference in terms device programmability
between MPU6050 and MPU6500.
These are different registers, which differs between MPU6050 and
MPU6500.

Addr	Name
---------------------
1E 	LP_ACCEL_ODR
6C	PWR_MGMT_2
77	XA_OFFSET_H
78	XA_OFFSET_L
7A	YA_OFFSET_H
7B	YA_OFFSET_L
7D	ZA_OFFSET_H
7E	ZA_OFFSET_L

But the current MPU6050 driver doesn't use registers which are different
except PWR_MGMT_2. The difference is support of "LP_WAKE_CTRL" at bit6-7
in MPU6050 mode. In MPU6500 they are not defined.
In current mpu6050 driver, only values used for this register are for
standby mode for gyro and accelerometer.
In both case frequency of wakeups is set to default and not using
bit 6-7.

So this driver van as well support MPU6500. In addition MPU6500 can
run MPU6050 mode by changing device trim settings.

So changing config comments to allow MPU6500 to use this driver.
When the driver is enhanced to support more functions, i2c driver
data INV_MPU6500 or "WHO_AM_I" register can be used to add additional
functionality.

* Lite-on ltr501 ambient light and proximity sensor

Cleanups
* Clean up some dead comments in max1363
* Drop some obsolete variables in adjd_s311 and tcs3472 left over from
  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.
