Created a host command to set/get various motion sensor parameters and added an ectool command to use that host command. The host command is created such that the first argument is a sub-command. Sub-commands created include: dump: dumps all current motion sensor data info: returns general information about each motion sensor ec_rate: set/get the EC sampling rate of sensors sensor_range: set/get the sensor range (ie +/- 2G,4G,8G) sensor_odr: set/get the sensor output data rate (ie 50Hz, 100Hz, ...) For sensor_range and sensor_odr parameters, since the host doesn't know what are valid values for the parameter, the host can specify to round up or down to the nearest valid value. For example, the host can specify to set the output data rate to at least 100Hz, and the EC will return the closest valid output data rate that is at least 100Hz.

I tested the EC sampling rate was 1000ms by running lidangle on and making sure samples were displayed roughly every second. I verified the sensor odr and range by defining CONFIG_CMD_ACCELS and typing: > accelrange 0 8 > accelrate 0 50000 Change-Id: I444e2f0eafabd607f1c7aa78b5c4e91f6cb06387 Signed-off-by: Alec Berg <alecaberg@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/192064 Reviewed-on: https://chromium-review.googlesource.com/193307 Reviewed-by: Randall Spangler <rspangler@chromium.org>
