2022-01-23iio: st_sensors: don't always auto-enable I2C and SPI interface driversNikita Yushchenko1-15/+22
This patch makes I2C and SPI interface drivers for STMicroelectronics sensor chips individually selectable via Kconfig. The default is kept unchanged - I2C and SPI interface drivers are still selected by default if the corresponding bus support is available. However, the patch makes it possible to explicitly disable drivers that are not needed for a particular target.

2021-09-14iio: gyro: remove dead config dependencies on INPUT_MPU3050Lukas Bulwahn1-1/+0
Commit b1fe0cf06f92 ("Input: delete MPU3050 driver") deletes the superseded MPU3050 driver and its corresponding config INPUT_MPU3050. The dependencies on the superseding driver in ./drivers/iio/gyro/Kconfig to ensure that the two drivers are not built into the same kernel is a dead dependency and not required anymore. So, remove those config dependencies on INPUT_MPU3050 for MPU3050_I2C. This issue was detected with ./scripts/checkkconfigsymbols.py.

2021-05-10iio: hid-sensors: select IIO_TRIGGERED_BUFFER under HID_SENSOR_IIO_TRIGGERAlexandru Ardelean1-1/+0
During commit 067fda1c065ff ("iio: hid-sensors: move triggered buffer setup into hid_sensor_setup_trigger"), the iio_triggered_buffer_{setup,cleanup}() functions got moved under the hid-sensor-trigger module. The above change works fine, if any of the sensors get built. However, when only the common hid-sensor-trigger module gets built (and none of the drivers), then the IIO_TRIGGERED_BUFFER symbol isn't selected/enforced. Previously, each driver would enforce/select the IIO_TRIGGERED_BUFFER symbol. With this change the HID_SENSOR_IIO_TRIGGER (for the hid-sensor-trigger module) will enforce that IIO_TRIGGERED_BUFFER gets selected. All HID sensor drivers select the HID_SENSOR_IIO_TRIGGER symbol. So, this change removes the IIO_TRIGGERED_BUFFER enforcement from each driver.

Provide a way for continuous data capture by setting up buffer support. The data ready signal exposed at the SYNC pin of the ADXRS290 is exploited as a hardware interrupt which triggers to fill the buffer. Triggered buffer setup was tested with both hardware trigger (DATA_RDY) and software triggers (sysfs-trig & hrtimer).

2016-10-25iio: gyro: Add driver for the MPU-3050 gyroscopeLinus Walleij1-0/+17
This adds a new driver for the Invensense MPU-3050 gyroscope. This driver is based on information from the rough input driver in drivers/input/misc/mpu3050.c and the scratch misc driver posted by Nathan Royer in 2011. Some years have passed but this is finally a fully-fledged driver for this gyroscope. It was developed and tested on the Qualcomm APQ8060 Dragonboard. The driver supports both raw and buffered input. It also supports the internal trigger mechanism by registering a trigger that can fire in response to the internal sample engine of the component. In addition to reading out the gyroscope sensor values, the driver also supports reading the temperature from the sensor. The driver currently only supports I2C but the MPU-3050 can also be used from SPI, so the I2C portions are split in their own file and we just use regmap to access all registers, so it will be trivial to plug in SPI support if/when someone has a system requiring this. To conserve power, the driver utilizes the runtime PM framework and will put the sensor in off mode and disable the regulators when unused, after a timeout of 10 seconds. The fullscale can be set for the sensor to 250, 500, 1000 or 2000 deg/s. This corresponds to scale values of rougly 0.000122, 0.000275, 0.000512 or 0.001068. By writing such values (or close to these) into "in_anglevel_scale", the corresponding fullscale can be chosen. It will default to 2000 deg/s (~35 rad/s). The gyro component can have DC offsets on all axes. These can be compensated using the standard sysfs ABI property "in_anglevel_[xyz]_calibbias". This is in positive/negative values of the raw values, so a suitable calibration bias can be determined by userspace by reading the "in_anglevel_[xyz]_raw" for a few iterations while holding the sensor still, create an average integer, and writing the negative inverse of that into "in_anglevel_[xyz]_calibbias". After this the hardware will automatically subtract the bias, also when using buffered readings. Since the MPU-3050 has an outgoing I2C port it needs to act as an I2C mux. This means that the device is switching I2C traffic to devices beyond it. On my system this is the only way to reach the accelerometer. The "sensor fusion" ability of the MPU-3050 to directly talk to the device on the outgoing I2C port is currently not used by the driver, but it has code to allow I2C traffic to pass through so that the Linux kernel can reach the device on the other side with a kernel driver.
