Gwendal Grignou 11b86c7004 platform/chrome: Add cros_ec_accel_legacy driver
Add driver to support older EC firmware that only support deprecated
ec command. Rely on ACPI memory map register to access sensor
information.
Present same interface as the regular cros_ec sensor stack:
- one iio device per accelerometer
- use HTML5 axis definition
- use iio abi units
- accept calibration calls, but do nothing
Chrome can use the same code than regular cros_ec sensor stack to
calculate orientation and lid angle.

Linus Walleij ed8959f40a iio: accel: fix Kconfig warning
commit 762227721f
"iio: accel: st_accel: handle deprecated bindings"
attempted to be smart and let users use the old I2C
driver and the new SPI driver, or the old SPI driver and
the new I2C driver in combination for the LIS3LV02,
and put the restrictions on the I2C and SPI subdrivers
not not be combined with the old subdrivers.

This doesn't work since the IIO ST accel top-level
component selects the I2C and SPI subdrivers, resulting
in the following Kconfig noise:

warning: (IIO_ST_ACCEL_3AXIS) selects IIO_ST_ACCEL_I2C_3AXIS
which has unmet direct dependencies (IIO && !SENSORS_LIS3_I2C
&& IIO_ST_ACCEL_3AXIS && IIO_ST_SENSORS_I2C)
warning: (IIO_ST_ACCEL_3AXIS) selects IIO_ST_ACCEL_SPI_3AXIS
which has unmet direct dependencies (IIO && !SENSORS_LIS3_SPI
&& IIO_ST_ACCEL_3AXIS && IIO_ST_SENSORS_SPI)
(...)

This fixes the issue by putting the dependencies directly
in the top-level component instead, so that it never gets
to select its unselectable subcomponent.

Linus Walleij 762227721f iio: accel: st_accel: handle deprecated bindings
The earlier deployed LIS3LV02DL driver had already defined a few
DT bindings that need to be supported by the new more generic
driver and listed as compatible but deprecated bindings in the
documentation.

After this we can start to activate the new driver with the old
systems where applicable.

As part of this enablement: make us depend on the old drivers
not being in use so we don't get a kernel with two competing
drivers.

Linus Walleij 0427a106a9 iio: accel: kxsd9: Add triggered buffer handling
As is custom with all modern sensors, add a clever burst mode
that will just stream out values from the sensor and provide it
to userspace to do the proper offsetting and scaling.

This is the result when tested with an HRTimer trigger:

$ generic_buffer -a -c 10 -n kxsd9 -t foo
/sys/bus/iio/devices/iio:device1 foo

Columns shown are x, y, z acceleration, so a positive acceleration
of ~9.81 (shaky due to bad calibration) along the z axis. The
fourth column is the AUX IN which is floating on this system,
it seems to float up to the 2.85V VDD voltage.

To be able to cleanup the triggered buffer, we need to add .remove()
callbacks to the I2C and SPI subdrivers and call back into an
exported .remove() callback in the core.

Add support for Freescale MMA7455L/MMA7456L 3-axis in 10-bit mode for
I2C and SPI bus. This rather simple driver that currently doesn't
support all the hardware features of MMA7455L/MMA7456L.

Tested on Embedded Artist's LPC4357 Dev Kit with MMA7455L on I2C bus.

Data sheets for the two devices can be found here:

Teodora Baluta 75b6548f17 iio: accel: add support for Memsic MXC6255XC sensor
This patch adds a minimal implementation for the Memsic MXC6255XC
orientation sensing accelerometer. The supported operations are reading
raw acceleration values for X/Y axis that can be scaled using the
exposed scale.

Martin Kepplinger 417e008ba9 iio: mma8452: add support for MMA8652FC and MMA8653FC
MMA8652FC and MMA8653FC don't provide the transient interrupt source, so
the motion interrupt source is used by providing a new iio_chan_spec
definition, so that other supported devices are not affected by this.

Datasheets for the newly supported devices are available at Freescale's
website:

It creates a devicetree bindings file to document the new functionality

Irina Tirdea 40cb761306 iio: add driver for Freescale MMA9553
Add support for Freescale MMA9553L Intelligent Pedometer Platform.

The following functionalities are supported:
 - step counter (counts the number of steps using a HW register)
 - step detector (generates an iio event at every step the user takes)
 - activity recognition (rest, walking, jogging, running)
 - speed
 - calories
 - distance

To get accurate pedometer results, the user's height, weight and gender
need to be configured.

http://www.freescale.com/files/sensors/doc/data_sheet/MMA955xL.pdf.

To support more devices from this family, we need to split the
mma9551 driver so we can export the common functions that will
be used by other mma955x drivers.
