| * | iio: imu: adis: Use spi cs inactive delayRamona Gradinariu2023-11-161-12/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A delay is needed each time the chip selected becomes inactive, even after burst data readings are performed. Currently, there is no delay added after a burst reading and in case a new SPI transfer is performed before the needed delay, the adis device becomes unresponsive until reset. This commit is adding the needed delay directly to the spi driver, using the cs_inactive parameter, in case it is not set and is removing the additional chip select change delay present in adis APIs to remove the double delay.

Only took 13 years :) One small patch added then reverted due to a report of test breakage (ashai-kasei,ak8975: Drop deprecated enums.) An immutable branch was used for some hid-senors changes in case there was a need to take them into the HID tree as well. New device support ----------------- adi,hmc425a - Add support for HMC540SLP3E broadband 4-bit digital attenuator. kionix,kx022a - Add support for the kx132-1211 accelerometer. Require significant driver rework to enable this including add a chip type specific structure to deal with the chip differences. - Add support for the kx132acr-lbz accelerometer (subset of the kx022a feature set). lltc,ltc2309 - New driver for this 8 channel ADC. microchip,mcp3911 - Add support for rest of mcp391x family of ADCs (there are various differences beyond simple channel count variation. Series includes some general driver cleanup. microchip,mcp3564 - New driver for MCP3461, MCP3462, MCP3464, MCP3541, MCP3562, MCP3564 and their R variants of 16/24bit ADCs. A few minor fixed followed. rohm,bu1390 - New driver for this pressure sensor. Staging graduation ------------------ adi,ad1210 (after 13 or so years :) - More or less a complete (step-wise) rewrite of this resolver driver to bring it up to date with modern IIO standards. The fault signal handling mapping to event channels was particularly complex and significant part of the changes. Features -------- iio-core - Add chromacity and color temperature channel types. adi,ad7192 - Oversampling ratio control (called fast settling in datasheet). adi,adis16475 - Add core support and then driver support for delta angle and delta velocity channels. These are intended for summation to establish angle and velocity changes over larger timescales. Fix was needed for alignment after the temperature channel. Further fix reduced set of devices for which the buffer support was applicable as seems burst reads don't cover these on all devices. hid-sensors-als - Chromacity and color temperatures support including in amd sfh. stx104 - Add support for counter subsystem to this multipurpose device. ti,twl6030 - Add missing device tree binding description. Clean up and minor fixes. ------------------------ treewide - Drop some unused declarations across IIO. - Make more use of device_get_match_data() instead of OF specific approaches. Similar cleanup to sets of drivers. - Stop platform remove callbacks returning anything by using the temporary remove_new() callback. - Use i2c_get_match_data() to cope nicely with all types of ID table entry. - Use device_get_match_data() for various platform device to cope with more types of firmware. - Convert from enum to pointer in ID tables allowing use of i2c_get_match_data(). - Fix sorting on some ID tables. - Include specific string helper headers rather than simply string_helpers.h docs - Better description of the ordering requirements etc for available_scan_masks. tools - Handle alignment of mixed sizes where the last element isn't the biggest correctly. Seems that doesn't happen often! adi,ad2s1210 - Lots of work from David Lechner on this driver including a few fixes that are going with the rework to avoid slowing that down. adi,ad4310 - Replace deprecated devm_clk_register() adi,ad74413r - Bring the channel function setting inline with the datasheet. adi,ad7192 - Change to FIELD_PREP(), FIELD_GET(). - Calculate f_order from the sinc filter and chop filter states. - Move more per chip config into data in struct ad7192_chip_info - Cleanup unused parameter in channel macros. adi,adf4350 - Make use of devm_* to simplify error handling for many of the setup calls in probe() / tear down in remove() and error paths. Some more work to be done on this one. - Use dev_err_probe() for errors in probe() callback. adi,adf4413 - Typo in function name prefix. adi,adxl345 - Add channel scale to the chip type specific structure and drop using a type field previously used for indirection. asahi,ak8985 - Fix a mismatch introduced when switching from enum->pointers in the match tables. amlogic,meson - Expand error logging during probe. invensense,mpu6050 - Support level-shifter control. Whilst no one is sure exactly what this is doing it is needed for some old boards. - Document mount-matrix dt-binding. mediatek,mt6577 - Use devm_clk_get_enabled() to replace open coded version and move everything over to being device managed. Drop now empty remove() callback. Fix follows to put the drvdata back. - Use dev_err_probe() for error reporting in probe() callback. memsic,mxc4005 - Add of_match_table. microchip,mcp4725 - Move various chip specific data from being looked up by chip ID to data in the chip type specific structure. silicon-labs,si7005 - Add of_match_table and entry in trivial-devices.yaml st,lsm6dsx - Add missing mount-matrix dt binding documentation. st,spear - Use devm_clk_get_enabled() and some other devm calls to move everything over to being device managed. Drop now empty remove() callback. - Use dev_err_probe() to better handled deferred probing and tidy up error reporting in probe() callback. st,stm32-adc - Add a bit of additional checking in probe() to protect against a NULL pointer (no known path to trigger it today). - Replace deprecated strncpy() ti,ads1015 - Allow for edge triggers. - Document interrupt in dt-bindings. * tag 'iio-for-6.7a' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (201 commits) iio: Use device_get_match_data() iio: adc: MCP3564: fix warn: unsigned '__x' is never less than zero. dt-bindings: trivial-devices: add silabs,si7005 iio: si7005: Add device tree support drivers: imu: adis16475.c: Remove scan index from delta channels dt-bindings: iio: imu: st,lsm6dsx: add mount-matrix property iio: resolver: ad2s1210: remove of_match_ptr() iio: resolver: ad2s1210: remove DRV_NAME macro iio: resolver: ad2s1210: move out of staging staging: iio: resolver: ad2s1210: simplify code with guard(mutex) staging: iio: resolver: ad2s1210: clear faults after soft reset staging: iio: resolver: ad2s1210: refactor sample toggle staging: iio: resolver: ad2s1210: remove fault attribute staging: iio: resolver: ad2s1210: add label attribute support staging: iio: resolver: ad2s1210: add register/fault support summary staging: iio: resolver: ad2s1210: implement fault events iio: event: add optional event label support staging: iio: resolver: ad2s1210: rename DOS reset min/max attrs staging: iio: resolver: ad2s1210: convert DOS mismatch threshold to event attr staging: iio: resolver: ad2s1210: convert DOS overrange threshold to event attr ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When processing data read the full fifo data in 1 time. If there are several samples in the FIFO, it means we are experiencing system delay. In this case, it is better to read all data with 1 bus access than to add additional latency by doing several ones. This requires to use a bigger buffer depending on chip FIFO size and do an additional local data copy before sending. But the cost is minimal and behavior is still better like this under system heavy load.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We are currently synchronizing every time the data timestamp with the IT timestamp, leading to system jitter jamming timestamps. To fix that and keep it simple, let's just synchronize when the delta is bigger than the acceptable jitter, and keep synchronization at the jitter value. The result is much stable timestamps reflecting better the real physical value. Example @50Hz delta timestamp, * before: 20.123ms, 19.721ms, 20.023ms, 20.353ms, 19.821ms, ... * after: 20.173ms, 20.173ms, 20.173ms, 20.40ms, 20.173ms, ...

| | * iio: imu: st_lsm6dsx: discard samples during filters settling timeLorenzo Bianconi2023-03-113-8/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During digital filters settling time the driver is expected to drop samples since they can be corrupted. 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.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | function call Supporting multi-cs in spi drivers would require the chip_select & cs_gpiod members of struct spi_device to be an array. But changing the type of these members to array would break the spi driver functionality. To make the transition smoother introduced four new APIs to get/set the spi->chip_select & spi->cs_gpiod and replaced all spi->chip_select and spi->cs_gpiod references with get or set API calls. While adding multi-cs support in further patches the chip_select & cs_gpiod members of the spi_device structure would be converted to arrays & the "idx" parameter of the APIs would be used as array index i.e., spi->chip_select[idx] & spi->cs_gpiod[idx] respectively.
