Introduce the capability to drop a given number of samples according to the configured ODR. Add sample_to_discard for LSM6DSM-like sensors since new generation devices (e.g. LSM6DSO) support DRDY mask where corrupted samples are masked in hw with values greather than 0x7ffd so the driver can easily discard them. I have not added sample_to_discard support for LSM6DS3 or LSM6DS3H since I do not have any sample for testing at the moment.

iio: imu: st_lsm6dsx: add dts property to disable sensor-hub Introduce the capability to disable sensorhub through a device-tree property since there are some configurations where users want to explicitly disable sensor-hub auto-probing at bootstrap. A typical configuration is when the sensorhub clock/data lines are connected to a pull-up resistor since no slave sensors are connected to the i2c master. If SDO/SA0 line is connected to the same pull-up resistor, when the driver tries to probe slave devices connected on sensor-hub, it will force SDO/SA0 line to low, modifying the device i2c address.

For examples setting FS to 4g the in_accel_x_scale, in_accel_y_scale and in_accel_z_scale are 0.001196 on 6 decimal digits and the FS is 0.001196 × ((2^15) − 1) ~= 39.1893 m/s^2. Android CTS R10 SensorParameterRangeTest test expects a value greater than 39.20 m/s^2 so this test fails (ACCELEROMETER_MAX_RANGE = 4 * 9.80). Using 9 decimal digits the new scale factor is 0.001196411 and the FS now is 0.001196411 × ((2^15)−1) ~= 39.2028 m/s^2. This patch extends to IIO_VAL_INT_PLUS_NANO type the scaling factor to all IMU devices where SensorParameterRangeTest CTS test fails.

iio: remove explicit IIO device parent assignment This patch applies the semantic patch: @@ expression I, P, SP; @@ I = devm_iio_device_alloc(P, SP); ... - I->dev.parent = P; It updates 302 files and does 307 deletions. This semantic patch also removes some comments like '/* Establish that the iio_dev is a child of the i2c device */' But this is is only done in case where the block is left empty. The patch does not seem to cover all cases. It looks like in some cases a different variable is used in some cases to assign the parent, but it points to the same reference. In other cases, the block covered by ... may be just too big to be covered by the semantic patch. However, this looks pretty good as well, as it does cover a big bulk of the drivers that should remove the parent assignment.

iio: imu: st_lsm6dsx: Fix selection of ST_LSM6DS3_ID At the moment, attempting to probe a device with ST_LSM6DS3_ID (e.g. using the st,lsm6ds3 compatible) fails with: st_lsm6dsx_i2c 1-006b: unsupported whoami [69] ... even though 0x69 is the whoami listed for ST_LSM6DS3_ID. This happens because st_lsm6dsx_check_whoami() also attempts to match unspecified (zero-initialized) entries in the "id" array. ST_LSM6DS3_ID = 0 will therefore match any entry in st_lsm6dsx_sensor_settings (here: the first), because none of them actually have all 12 entries listed in the "id" array. Avoid this by additionally checking if "name" is set, which is only set for valid entries in the "id" array. Note: Although the problem was introduced earlier it did not surface until commit 52f4b1f19679 ("iio: imu: st_lsm6dsx: add support for accel/gyro unit of lsm9ds1") because ST_LSM6DS3_ID was the first entry in st_lsm6dsx_sensor_settings.

iio: imu: st_lsm6dsx: add support for accel/gyro unit of lsm9ds1 The LSM9DS1's accelerometer / gyroscope unit and it's magnetometer (separately supported in iio/magnetometer/st_magn*) are located on a separate i2c addresses on the bus. For the datasheet, see https://www.st.com/resource/en/datasheet/lsm9ds1.pdf Treat it just like the LSM6* devices and, despite it's name, hook it up to the st_lsm6dsx driver, using it's basic functionality. accelerometer and gyroscope are not independently clocked. It runs at the gyro frequencies if both are enabled, see chapter 7.12 of the datasheet. We could have handled this as a single IIO device but we have split it up to be more consistent with the other more flexible devices. Despite supporting and testing the LSM9DS1, we call the gyro channels iio_chan_spec struct "st_lsm6ds0_gyro_channels" because the register description is equal. This suggests that supporting LSM6DS0 should be trivial to do. Signed-off-by: Martin Kepplinger <martin.kepplinger@puri.sm> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>

iio: imu: st_lsm6dsx: do not apply ODR configuration in write_raw handler This patch allows to avoid a transitory that occurs when a given sensor has been already enabled (e.g. gyroscope) and the user is configuring the sample frequency of the other one (e.g. accelerometer). The transitory lasts until the accelerometer is enabled. During that time slice the gyroscope ODR is incorrectly modified as well. At the end of the transitory both sensors work at the right frequency. Fix it introducing st_lsm6dsx_check_odr() routine to check ODR consistency in write_raw handler in order to apply frequency configuration just in st_lsm6dsx_set_odr() Fixes: 290a6ce11d93 (iio: imu: add support to lsm6dsx driver) Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@st.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
