* common: sensors: add extra sensor attributesNick Vaccaro2017-05-181-0/+6
| | | | | | | | | | | | | | | | | | | | | | Adds min_frequency and max_frequency to struct motion_sensor_t. New attributes min_frequency and max_frequency are now returned in ectool's MOTIONSENSE_CMD_INFO response. Incremented ectool's MOTIONSENSE_CMD_INFO version to version 3. Add constants for MIN_FREQUENCY and MAX_FREQUENCY to each sensor's header file. BRANCH=none BUG=chromium:615059 TEST=build/boot and verify MOTIONSENSE_CMD_INFO response on kevin, make buildall -j passes.

* motion_sense: Add more complex EC/AP sensor rate support.Gwendal Grignou2015-08-291-2/+2
| | | | | | | | | | | | | | | | | | | | | Add config settings for ODR and EC rate per requestor and per power state (1 for the AP, 3 for the EC). This way we can finely set ec rate and ODR depending on usage. On chromeos, AP is not setting frequency, so EC sets for different power state. On some platform, sensors can now be suspended in S3/S5. Allow EC oversampling when AP is only looking for a few samples. It is useful for double tap detection where high accelerator ODR is required.

* driver: lsm6ds0: Add bias offset codeGwendal Grignou2015-07-091-0/+5
| | | | | | | | | | | | | | | | Add code to store bias from AP at boot and correct raw data from accelerometer on the fly. Also return the raw data on 16 bits, as recommned by sysfs. BRANCH=smaug BUG=chromium:506101 TEST=check set and get offset works fine. Check value from accelerometer are sane (on Samus).

* cleanup: fix all the header guardsBill Richardson2015-06-181-3/+3
| | | | | | | | | | | | | | | This unifies all the EC header files to use __CROS_EC_FILENAME_H as the include guard. Well, except for test/ util/ and extra/ which use __TEST_ __UTIL_ and __EXTRA_ prefixes respectively.

* driver: Use common data structure to store default accel valuesGwendal Grignou2015-05-121-8/+0
| | | | | | | | | | | | | | | Move structure used by lms6ds0 to motion_sense.h, so that bosh driver can use the same mechanism. Use code to avoid reading chip range when reading data.

* lsm6ds0: Cache ODR and range on EC.Aseda Aboagye2015-04-201-0/+8
| | | | | | | | | | | | | | | | | | | | | | For the driver functions get_range and get_data_rate, each call would end up executing an i2c transaction even if the value had not changed. Therefore, I modified the lsm6ds0 driver to cache the output data rate as well as the range. This prevents unecessary i2c transactions from occuring. BUG=chromium:476226 TEST=Flashed EC on samus and verified that the accelrange and accelrate commands still worked and that the sensors were functional. TEST=Verified Double Tap still worked.

* Refactor accel / gyro driver to accomodate various configurationsShawn Nematbakhsh2014-08-191-0/+14
| | | | | | | | | | | | | | | | | | | 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.

* accel: add accel driver for lsm6ds0Alec Berg2014-04-231-0/+45
This adds the basics for the accelerometer potion only of the ST lsm6ds0 accel/gyro. Still need to add the acceleration interrupt functionality, and all of the gyro portion of the chip. BUG=none BRANCH=none TEST=Tested on a samus prototype hacked up to have the lsm6ds0 connected to the EC i2c bus. Added motion sense task to the samus tasklist, added accelerometer information to the samus board file, and tested console functions interacting with accelerometer. The data seems reasonable, and can successfully change data rate and range.
