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.

During probe the driver allocates dummy I2C devices (i2c_new_dummy())
but they aren't unregistered during driver remove or probe failure.
Additionally driver does not check the return value of i2c_new_dummy().
In case of error (i2c_new_device(): memory allocation failure or I2C
address cannot be used) this function returns NULL which is later
dereferenced by i2c_smbus_{read,write}_data() functions.
Fix issues by properly checking for i2c_new_dummy() return value and
unregistering I2C devices on driver remove or probe failure.

Ensure that querying the IIO buffer scan_mask returns a value of
0 or 1. Currently querying the scan mask has the value returned
by test_bit(), which returns either true or false. For some
architectures test_bit() may return -1 for true, which will appear
to return an error when returning from iio_scan_mask_query().
Additionally, it's important for the sysfs interface to consistently
return the same thing when querying the scan_mask.

This is because the at91_adc_caps structure is mandatory but is not filled when

The Xilinx XADC is a ADC that can be found in the series 7 FPGAs from Xilinx.
The XADC has a DRP interface for communication. Currently two different
frontends for the DRP interface exist. One that is only available on the ZYNQ
family as a hardmacro in the SoC portion of the ZYNQ. The other one is available
on all series 7 platforms and is a softmacro with a AXI interface. This driver
supports both interfaces and internally has a small abstraction layer that hides
the specifics of these interfaces from the main driver logic.
The ADC has a couple of internal channels which are used for voltage and
temperature monitoring of the FPGA as well as one primary and up to 16 channels
auxiliary channels for measuring external voltages. The external auxiliary
channels can either be directly connected each to one physical pin on the FPGA
or they can make use of an external multiplexer which is responsible for
multiplexing the external signals onto one pair of physical pins.
The voltage and temperature monitoring channels also have an event capability
which allows to generate a interrupt when their value falls below or raises
above a set threshold.
Buffered sampling mode is supported by the driver, but only for AXI-XADC since
the ZYNQ XADC interface does not have capabilities for supporting buffer mode
(no end-of-conversion interrupt). If buffered mode is supported the driver will
register two triggers. One "xadc-samplerate" trigger which will generate samples
with the configured samplerate. And one "xadc-convst" trigger which will
generate one sample each time the CONVST (conversion start) signal is asserted.

The event code currently holds a spinlock with IRQs disabled while calling
kfifo_to_user(). kfifo_to_user() can generate a page fault though, which means
we have to be able to sleep, which is not possible if the interrupts are
disabled. The good thing is that kfifo handles concurrent read and write access
just fine as long as there is only one reader and one writer, so we do not any
locking to protect against concurrent access from the read and writer thread. It
is possible though that userspace is trying to read from the event FIFO from
multiple concurrent threads, so we need to add locking to protect against this.
This is done using a mutex. The mutex will only protect the kfifo_to_user()
call, it will not protect the waitqueue. This means that multiple threads can be
waiting for new data and once a new event is added to the FIFO all waiting
threads will be woken up. If one of those threads is unable to read any data
(because another thread already read all the data) it will go back to sleep. The
only remaining issue is that now that the clearing of the BUSY flag and the
emptying of the FIFO does no longer happen in one atomic step it is possible
that a event is added to the FIFO after it has been emptied and this sample will
be visible the next time a new event file descriptor is created. To avoid this
rather move the emptying of the FIFO from iio_event_chrdev_release to
iio_event_getfd().

name_format already contains the final name and no format characters. So the
code basically reads:
dev_attr->attr.name = kstrdup(GFP_KERNEL, name_format);
if (dev_attr->attr.name == NULL)
...
kfree(name_format);
Which means we can save one alloc and free pair per attribute name if we
directly assign name_format to dev_attr->attr.name.

First set of new drivers and cleanups for IIO in the 3.15 cycle.
New drivers:
* si7005 relative humidity and temperature sensor
* 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.
In kernel version 3.13, devm_regulator_get() may return no error
if a regulator is undeclared. regulator_get_voltage() will return
-EINVAL if this happens. This causes the driver to fail loading if
the vref regulator is not declared.
Since vref is optional, call devm_regulator_get_optional instead.

This driver was not complying with the ABI and the purpose of this patch
is to bring it inline so that userspace will correctly identify the channels.
Should use channel modifiers (X/Y/Z), not channel indices
timestamp channel has scan index 3, not 4

This is necessary since timestamp is calculated as the last element
in iio_compute_scan_bytes().
Without this fix any userspace code reading the layout of the buffer via
sysfs will incorrectly interpret the data leading some nasty corruption.
