iio: imu: inv_icm42600: delete unneeded update watermark call

2024-06-21T12:40:28Z

commit 245f3b149e6cc3ac6ee612cdb7042263bfc9e73c upstream. Update watermark will be done inside the hwfifo_set_watermark callback just after the update_scan_mode. It is useless to do it here.

iio: imu: bmi323: Fix trigger notification in case of error

2024-06-21T12:40:27Z

commit bedb2ccb566de5ca0c336ca3fd3588cea6d50414 upstream. In case of error in the bmi323_trigger_handler() function, the function exits without calling the iio_trigger_notify_done() which is responsible for informing the attached trigger that the process is done and in case there is a .reenable(), to call it.

Jonathan writes: IIO: 1st set of new device support, features and cleanup for 6.9 IIO Backend support =================== New approach from Nuno Sa to the problem of reuse of drivers with IIO devices that are actually the combination of a highspeed chip and an FPGA core handling the data capture and flows. It will hopefully also apply to some other split designs. The ad9467 and axi-adi drivers are converted over to this framework. New device support ================== adi,admfm2000 - New driver for this dual microwave down converter. ams,as73211 - Add support for as7331 UV sensor. richtek,rtq6056 - Add support for related parts RTQ6053 and RTQ6059 st,lsm6dsx - Add ASM330LHHXG1 accelerometer and gyro support (mainly IDs) ti,ads1298 - New driver for this medical ADC. Features ======== tests - Unit tests for the gain-time-scale helper library. bosch,bmi088 - I2C support. bosh,bmi160 - Add 10EC5280 ACPI ID. Used in a number of devices that won't get fixed. The ID is actually a PCI ID belonging to realtech. No response was received to earlier attempts to notify them of this. The manufacturers of some devices have replied to say they will not fix this incorrect ID. Add the ID and hope it isn't a problem. bosch,bmi323 - Add BOSC0200 ACPI ID. Note this is a duplicate of one in the bmc150 driver (it appears these parts share a windows driver). Both drivers perform an ID check that is safe on the other part before successfully probing. hid-sensors-als - Add color temperature and chromaticity support. Note this is a replacement for the series reverted in 6.8 that correctly handles all the potential channel combinations. honeywell,hsc030pa - Triggered buffer support (after driver cleanup). honeywell,mprls00025pa - Improved error handling. - New DT binding to allow use of part number triplet as provided in data sheet to specify equivalent of most of the binding more efficiently. - SPI support. memsic,mxc4005 - ACPI ID MDA6655 as seen in the Chuwi Minibook X 2023 ti,hdc3020 - Add threshold event support (after some driver cleanup) veml,vcnl4000 - Switch to high resolution proximity measurement. Cleanup ======= Various minor typo fixes and better use of defines etc. Treewide - Stop using ACPI_PTR(). The savings in space are small and not worth the complexity of __maybe_unused of ifdef guards. To avoid use in new IIO drivers based on copy and paste, clean it out. - cleanup.h based handling of iio_device_claim_direct_mode()/ iio_device_release_direct_mode() using scope_cond_guard(). In many drivers this is combined with other automated cleanup to give maximum simplifications. An initial set of drivers are converted over to this infrastructure. Tools - Use rewinddir() instead of seekdir() to return to start of file. core - Make iio_bus_type constant. adi,ad16475 - Use irq_get_trigger_type() instead of opencoding. adi,ad16480 - Use irq_get_trigger_type() instead of opencoding. adi,ad-sigma-delta - Avoid overwriting IRQ flags if provided by firmware. ams,as73211 - Use IIO_VAL_FRACTIONAL for scales to simplify the code and potentially improve accuracy. gts-library - Use a div64_u64() instead of a loop to do a division. honeywell,mprls00025pa - Clean up dt-binding doc. - Drop defaults when DT binding not providing values. Very unlikely these were useful given they were wrong for vast majority of supported devices. - Whitespace cleanup miramems,da280 - Use i2c_get_match_data() to replace hand rolled ACPI matching code. semtech,sx9324 - Avoid unnecessary copying of property strings. st,lsm6dsx - Improve docs, particularly wrt to making addition of new device support less noisy. st,lsm9ds0 - Use dev_err_probe() in all probe() error handling. - Improved header includes. - Tidy up termination of ID tables. ti,ads1014 - Correct upper bound on PGA (wrong value had no actual impact) ti,afe4403/4404 - devm_ useage to simplify error handling in probe() and allow() remove to be dropped. voltage-divider - Add dt-binding for io-channel-cells to allow such a device to be both an IIO consumer and IIO producer at the same time. * tag 'iio-for-6.9a' of http://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (106 commits) iio: imu: bmi323: Add ACPI Match Table iio: accel: bmc150: Document duplicate ACPI entries with bmi323 driver iio: adc: ti-ads1298: Add driver dt-bindings: iio: adc: ti-ads1298: Add bindings iio: pressure: hsc030pa add triggered buffer iio: pressure: hsc030pa add mandatory delay iio: pressure: hsc030pa: update datasheet URLs iio: pressure: hsc030pa: include cleanup iio: pressure: hsc030pa: use signed type to hold div_64() result dt-bindings: iio: pressure: honeywell,hsc030pa.yaml add spi props iio: st_sensors: lsm9ds0: Use common style for terminator in ID tables iio: st_sensors: lsm9ds0: Don't use "proxy" headers iio: st_sensors: lsm9ds0: Use dev_err_probe() everywhere iio: adc: adi-axi-adc: move to backend framework iio: adc: ad9467: convert to backend framework iio: add the IIO backend framework iio: buffer-dmaengine: export buffer alloc and free functions of: property: add device link support for io-backends dt-bindings: adc: axi-adc: update bindings for backend framework dt-bindings: adc: ad9467: add new io-backend property ...

iio: imu: inv_mpu6050: fix frequency setting when chip is off

2024-02-25T11:42:12Z

Track correctly FIFO state and apply ODR change before starting the chip. Without the fix, you cannot change ODR more than 1 time when data buffering is off. This restriction on a single pending ODR change should only apply when the FIFO is on.
