59138ad097 motion_sense: Allow multiple IRQ based sensors
Add a mask of custom events reserved for IRQ based sensors.
Copy data from raw_xzy to xyz while filling the FIFO
when FIFO is enabled.

BRANCH=smaug
TEST=Test with si1141 driver, check irq works for both driver.

e095bad64e driver: bmi160 Add code for calibration
Add code for set/getting calibration data on bmi160
Add code to perform FOC (Fast Online Calibration) on bmi160.
Add delay after getting out of suspend to be sure sensor is
available.

BRANCH=smaug
TEST=Check sensors are properly calibrated on Smaug:
Perform calibration:
echo 1 > /sys/bus/iio/devices/iio:device1/calibrate
Read calibration values:
cat /sys/bus/iio/devices/iio:device1/*_calibbias
Check the values are translated properly.
Write calibration values and check it affects the
sensor output.

a7c4132d25 driver: bmi160: Add FIFO and interrupt support
Add FIFO support, where bmi160 hardware FIFO is copied in local fifo.
Add rudimentary support for single/double tap and lift detection.

BUG=chrome-os-partner:39900
BRANCH=smaug
TEST=Check on F411 that FIFO data is retrieved and correct.
Check on Smaug as well, with proper kernel the collect the FIFO:
- check that increasing sampling_frequency we are collecting
the FIFO less often
- check no frames are lost.
- check tap/lift interrupts are working
- if latency is less than 100ms, check we are collecting much faster.

fc17034c52 motion: Add commands for calibration
Move calibration in the EC to returns raw value with offset already
applied, as recommended by iio interface.

BRANCH=smaug
TEST=On Samus, with kernel change CL:283103
Check raw value are returned properly.

4b154c6f95 motion: Add decoding for MOTION_CMD_DUMP v1 command
MOTIONSENSE_CMD_DUMP is deprecated, replaced with MOTIONSENSE_CMD_GET_DATA
Also use vector_3_t instead of x,y,z

ectool motionsense commands only work with newer firmware, to
handle a dynamic number of sensors.
- The host sends the number of sensor it has allocated space for.
- If 0, the EC just sends the number of sensors available
- Otherwise returns sensor information up to the limit imposed by the host.

Remove MOTIONSENSE_GET_STATUS: not needed. It is only useful for LPC,
to guarantee atomicity of the data.
Remove MOTIONSENSE_GET_DATA: not needed since we increase the version
number of MOTIONSENSE command.

BUG=chrome-os-partner:31071,chromium:430792
BRANCH=ToT
TEST=Compile. On a firmware that support the new command:
/usr/sbin/ectool --name=cros_sh motionsense
Motion sensing active
Sensor 0: 92    15      1030
Sensor 1: -94   -63     718
/usr/sbin/ectool --name=cros_sh motionsense active
0
On a machine with older firmware (samus), check these
functions are not working anymore.

316f369f1c samus: add tap for battery
Adds double tap detection for samus. When user double taps
in S3 or lower to show battery state of charge on lightbar.

BUG=chrome-os-partner:29041
BRANCH=samus
TEST=make buildall
Tap the lid in S3 or lower.

7d40063d46 samus: added gyro support for lsm6ds0
Changed motion_sense task to assume sensors are unpowered in G3
and re-initialize sensors every time coming out of G3.

Added EC command line test utils as well.
Fixed some bug during unit tests.

BUG=chrome-os-partner:27313,27320
BRANCH=ToT
TEST=Verified on Samus.

Tested with accel EC CLIs
accelread, accelrange, accelrate, accelres

Tested accelcalib, a ACCEL calibration util, and it succeeded.

Tested sysfs interface:
cd /sys/bus/iio/devices/iio:device1
 cat in_accel_*_gyro_raw

a048d76e0d Refactor accel / gyro driver to accomodate various configurations
Previously our accel / gyro drivers assumed that we had exactly two of
each identical part in the system. Some systems may have different
configurations, so allow this to be specified at the board-level.

Note that our motion_sense algorithm currently assumes that we have one
accelerometer in the lid and one in the base -- we'll need to fix that
in another CL.

BUG=chrome-os-partner:27320
TEST=Compile-only. Tested in future Samus commit.
BRANCH=None.
