warning.
As per Documentation/timers/timers-howto.txt Msleep < 20ms can sleep for
up to 20ms. so use usleep_range.

Currently mount matrix is allowed in Device Tree, though there is
no technical issue to extend it to support ACPI.
Convert the function to use device_property_read_string_array() and
thus allow to read mount matrix from ACPI if available.
Example of use in _DSD method:
Name (_DSD, Package ()
{
ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
Package ()
{
Package () { "mount-matrix", Package() {
"1", "0", "0",
"0", "0.866", "0.5",
"0", "-0.5", "0.866",
} },
}
})
At the same time drop the "of" prefix from its name and
convert current users.
No functional change intended.

According to the datasheet, the last bit of CHIP_ID register controls
I2C bus, and the first one is unused. Handle this correctly.
Note that there are chips out there that have a value such that
the id check currently fails.

The newly added mpu3050 driver has two initializations for the
module owner, which causes a warning for 'make W=1':
include/linux/export.h:37:21: error: initialized field overwritten [-Werror=override-init]
drivers/iio/gyro/mpu3050-core.c:749:19: note: in expansion of macro 'THIS_MODULE'
This removes one of the two.

This adds a new driver for the Invensense MPU-3050 gyroscope.
This driver is based on information from the rough input driver
in drivers/input/misc/mpu3050.c and the scratch misc driver
posted by Nathan Royer in 2011. Some years have passed but this
is finally a fully-fledged driver for this gyroscope. It was
developed and tested on the Qualcomm APQ8060 Dragonboard.
The driver supports both raw and buffered input. It also
supports the internal trigger mechanism by registering a trigger
that can fire in response to the internal sample engine of the
component. In addition to reading out the gyroscope sensor
values, the driver also supports reading the temperature from
the sensor.
The driver currently only supports I2C but the MPU-3050 can
also be used from SPI, so the I2C portions are split in their
own file and we just use regmap to access all registers, so
it will be trivial to plug in SPI support if/when someone has
a system requiring this.
To conserve power, the driver utilizes the runtime PM
framework and will put the sensor in off mode and disable the
regulators when unused, after a timeout of 10 seconds.
The fullscale can be set for the sensor to 250, 500, 1000 or
2000 deg/s. This corresponds to scale values of rougly 0.000122,
0.000275, 0.000512 or 0.001068. By writing such values (or close
to these) into "in_anglevel_scale", the corresponding fullscale
can be chosen. It will default to 2000 deg/s (~35 rad/s).
The gyro component can have DC offsets on all axes. These can be
compensated using the standard sysfs ABI property
"in_anglevel_[xyz]_calibbias". This is in positive/negative
values of the raw values, so a suitable calibration bias can be
determined by userspace by reading the "in_anglevel_[xyz]_raw"
for a few iterations while holding the sensor still, create an
average integer, and writing the negative inverse of that into
"in_anglevel_[xyz]_calibbias". After this the hardware will
automatically subtract the bias, also when using buffered
readings.
Since the MPU-3050 has an outgoing I2C port it needs to act as
an I2C mux. This means that the device is switching I2C traffic
to devices beyond it. On my system this is the only way to reach
the accelerometer. The "sensor fusion" ability of the MPU-3050
to directly talk to the device on the outgoing I2C port is
currently not used by the driver, but it has code to allow I2C
traffic to pass through so that the Linux kernel can reach the
device on the other side with a kernel driver.

$ generic_buffer -a -c10 -n mpu3050
