70618035 - iio: hid-sensors: select IIO_TRIGGERED_BUFFER under HID_SENSOR_IIO_TRIGGER

Wed, 14 Apr 2021 08:49:55 +0000

iio: hid-sensors: select IIO_TRIGGERED_BUFFER under HID_SENSOR_IIO_TRIGGERDuring commit 067fda1c065ff ("iio: hid-sensors: move triggered buffersetup into hid_sensor_setup_trigger"), theiio_triggered_buffer_{setup,cleanup}() functions got moved under thehid-sensor-trigger module.The above change works fine, if any of the sensors get built. However, whenonly the common hid-sensor-trigger module gets built (and none of thedrivers), then the IIO_TRIGGERED_BUFFER symbol isn't selected/enforced.Previously, each driver would enforce/select the IIO_TRIGGERED_BUFFERsymbol. With this change the HID_SENSOR_IIO_TRIGGER (for thehid-sensor-trigger module) will enforce that IIO_TRIGGERED_BUFFER getsselected.All HID sensor drivers select the HID_SENSOR_IIO_TRIGGER symbol. So, thischange removes the IIO_TRIGGERED_BUFFER enforcement from each driver.Fixes: 067fda1c065ff ("iio: hid-sensors: move triggered buffer setup into hid_sensor_setup_trigger")Reported-by: Thomas Deutschmann Cc: Srinivas Pandruvada Signed-off-by: Alexandru Ardelean Acked-by: Srinivas Pandruvada Link: https://lore.kernel.org/r/20210414084955.260117-1-aardelean@deviqon.comSigned-off-by: Jonathan Cameron List of files: /linux-6.15/drivers/iio/gyro/Kconfig

3904b28e - iio: gyro: Add driver for the MPU-3050 gyroscope

Tue, 25 Oct 2016 14:15:54 +0000

iio: gyro: Add driver for the MPU-3050 gyroscopeThis adds a new driver for the Invensense MPU-3050 gyroscope.This driver is based on information from the rough input driverin drivers/input/misc/mpu3050.c and the scratch misc driverposted by Nathan Royer in 2011. Some years have passed but thisis finally a fully-fledged driver for this gyroscope. It wasdeveloped and tested on the Qualcomm APQ8060 Dragonboard.The driver supports both raw and buffered input. It alsosupports the internal trigger mechanism by registering a triggerthat can fire in response to the internal sample engine of thecomponent. In addition to reading out the gyroscope sensorvalues, the driver also supports reading the temperature fromthe sensor.The driver currently only supports I2C but the MPU-3050 canalso be used from SPI, so the I2C portions are split in theirown file and we just use regmap to access all registers, soit will be trivial to plug in SPI support if/when someone hasa system requiring this.To conserve power, the driver utilizes the runtime PMframework and will put the sensor in off mode and disable theregulators when unused, after a timeout of 10 seconds.The fullscale can be set for the sensor to 250, 500, 1000 or2000 deg/s. This corresponds to scale values of rougly 0.000122,0.000275, 0.000512 or 0.001068. By writing such values (or closeto these) into "in_anglevel_scale", the corresponding fullscalecan be chosen. It will default to 2000 deg/s (~35 rad/s).The gyro component can have DC offsets on all axes. These can becompensated using the standard sysfs ABI property"in_anglevel_[xyz]_calibbias". This is in positive/negativevalues of the raw values, so a suitable calibration bias can bedetermined by userspace by reading the "in_anglevel_[xyz]_raw"for a few iterations while holding the sensor still, create anaverage integer, and writing the negative inverse of that into"in_anglevel_[xyz]_calibbias". After this the hardware willautomatically subtract the bias, also when using bufferedreadings.Since the MPU-3050 has an outgoing I2C port it needs to act asan I2C mux. This means that the device is switching I2C trafficto devices beyond it. On my system this is the only way to reachthe accelerometer. The "sensor fusion" ability of the MPU-3050to directly talk to the device on the outgoing I2C port iscurrently not used by the driver, but it has code to allow I2Ctraffic to pass through so that the Linux kernel can reach thedevice on the other side with a kernel driver.Example usage with the native trigger:$ generic_buffer -a -c10 -n mpu3050iio device number being used is 0iio trigger number being used is 0No channels are enabled, enabling all channelsEnabling: in_anglvel_z_enEnabling: in_timestamp_enEnabling: in_anglvel_y_enEnabling: in_temp_enEnabling: in_anglvel_x_en/sys/bus/iio/devices/iio:device0 mpu3050-dev029607.142578 -0.117493 0.074768 0.012817 18078879715029639.285156 -0.117493 0.076904 0.013885 18088898233529696.427734 -0.116425 0.076904 0.012817 18098917803929742.857422 -0.117493 0.076904 0.012817 18108937774229764.285156 -0.116425 0.077972 0.012817 18118957418729860.714844 -0.115356 0.076904 0.012817 18128977270529864.285156 -0.117493 0.076904 0.012817 18138997152029910.714844 -0.115356 0.076904 0.013885 18149017048329917.857422 -0.116425 0.076904 0.011749 18159036974229975.000000 -0.116425 0.076904 0.012817 181690567075Disabling: in_anglvel_z_enDisabling: in_timestamp_enDisabling: in_anglvel_y_enDisabling: in_temp_enDisabling: in_anglvel_x_enThe first column is the temperature in millidegrees, then the x,y,zaxes in succession followed by the timestamp.
