* driver: BMM150: Set max frequency based on repetitions settingGwendal Grignou2017-10-301-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | The compass uses oversampling to produce accurate values. MAX_ODR is functions of the repetitions setting. 80Hz is too high, calculate the frequency based on preset setting. Currently, we use 'SPECIAL' that was calculated for Ryu. BUG=b:68394559 BRANCH=eve,reef,poppy TEST=Check with ectool motionsense info 3 the frequency is around 30Hz. Before: Min Frequency: 781 mHz Max Frequency: 80000 mHz After: Min Frequency: 781 mHz Max Frequency: 29579 mHz Check with AIDA64 the compass is not stuck and return changing values.

* driver: sensor: tune MAX_FREQGwendal Grignou2017-07-131-1/+1
| | | | | | | | | | | | | | | | | | | | Reduce maximum frequency of BMM150 compass to 80Hz, 800Hz is a typo. Reduce SI1141 maximum frequency to 50Hz: 100Hz is too high when polling mode is used. Fix up of CL:482703 BRANCH=eve, glados BUG=chromium:615059 TEST=On eve, check CTS test android.hardware.cts.SensorBatchingTests#testMagneticField_fastest_flush passes. Observed that dumpsys sensorservice returns compass maxRate at 80Hz instead of 200Hz.

* common: sensors: add extra sensor attributesNick Vaccaro2017-05-181-0/+3
| | | | | | | | | | | | | | | | | | | | | | 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.

* driver: bmm150: Use Bosch recommend repetitionGwendal Grignou2015-10-151-0/+2
| | | | | | | | | | | | | | To minimize noise, instead of using recommend preset from the documentation, use specific repetition value. BRANCH=smaug BUG=chrome-os-partner:45436 TEST=Check the noise is somewhat reduced, still not great.

| | | | | | | | | | | | | | | | To reduce noise the magnetometer measures in burst and average the data. Use "regular" presets: max frequency is limited to 100Hz. Using a more precise presets limit frequency to no more than 50Hz. BRANCH=smaug TEST=Check magnetomter still works.
