Merge tag 'iio-for-6.2a-take2' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next Jonathan writes: 1st set of IIO new device support, feature and cleanup for 6.2 (take2) We have finally managed to take the mlock mutex entirely private so as to avoid it being used for multiple purposes. Now it is just used to protect device mode transitions (typically to and from buffered capture). Includes merge of an immutable i2c branch to get the new i2c_client_get_device_id() (thanks to Wolfram for providing the branch). Based on rc3 to pick up some precursor fixes from early in the cycle and avoid an unnecessarily messy history. New device support * adi,ad4310 - New driver to support this very flexible measurement device including a 24 bit ADC. Later fix for documentation build issue. * adi,adxl355 - Add support of the ADXL359 accelerometer. * adi,ltc2983 - Support additional variants of the temperatures sensor: LTC2984 with an EEPROM LTC2985, LTC2986 with only 10 channels. * invensense,icm42600 - Add support for icm42631 (needed only ID and WHOAMI) * kionix,kx022a - New driver for this 3 axis accelerometer. * maxim,max11401 - New driver to support this 24-bit 10 channel ADC. Includes some new ABI to support configuration of notch filters. * mediatek,mt6370 - Add new driver to support the ADC part of the mt6370. * st,lsm6dsx - Add support for LSM6DSV accelerometer and gyroscope. Simple additional of chip specific data and IDs. - Add support for LSM6DSV16X accelerometer and gyroscope. Compatible with features currently implemented for the LSM6DSV. * st,stm32-adc - Add support for stm32pm13x SoCs. core / subsystem wide: - Add new IIO_STATIC_CONST_DEVICE_ATTR() which is a dance necessary to allow for the wrapping of attributes in the code that duplicates them for multiple buffers. - Harden against future issues with expectation that all buffer attributes are iio_dev_attrs by changing the code to take an array of pointers of the correct type. - Last transitions of drivers to local locks rather than missuses of mlock. - Add an iio_device_claim_buffer_mode() callback to avoid a race in the max30100 driver without directly using mlock. - Move mlock to the opaque IIO device structure to prevent misuse. - Add missing spi_device_id tables to support auto loading of modules. - Update some ADI maintainers in DT bindings. - A few more moves of bus drivers and core module sets to export name spaces. - Extensive use of new devm_regulator_get_enable() and friends. - Switch a bunch of i2c drivers to probe_new() including the bmp280 which makes use of the new i2c_client_get_device_id() helper to simplify this change. dt-bindings: - More use of spi-peripheral-props.yaml. Features * freescale,mpl115 - Use runtime PM to implement shutdown GPIO support. * melexis,mlx90632 - More sophisticated runtime power management - Provide access to sampling frequency. - Trivial follow up fixes. * microchip,mcp3911 - Support control of PGA. * st,lsm6dsx - Add support for software triggers for cases where the IRQ lines are not wired up. * vishay,vcnl4000 - Add control of integration time. Minor cleanups and fixes * adi,ad4130 - Improve ABI documentation formatting. - Kconfig dependency fixup. * adi,ad5758 - Minor dt binding fix. * adi,ad9834 - Tidy up line breaks. * adi,ade7854 - Minor improvement in code clarity by replacing a ternary. * adi,admv8818 - Harden code against hardware returning wrong values. * adi,adxl355 - Warn only if unknown device ID detected to allow for fall back device tree compatibles on future devices. * adi,ltc2983 - dt-bindings clarifications and general improvements. - Ensure DMA safe buffer for bulk writes without relying on current regmap implementation choices. * avago,adps9960 - Fix up a disconnect between event enable attributes and what was enabled. * bosch,bma400 - Switch to dev_err_probe() from open coded EPROBE_DEFER handling. * cosmic,cc10001 - Fully devm managed probe() and related tidying up. * meas,ms5611 - Add an example of spi-max-frequency. * meleixs,mlx90632 - Tidy up confusing error return value. - Style improvements. * multiplexer - Switch to dev_err_probe() from open coded EPROBE_DEFER handling. * qcom,spmi-vadc - Minor dt binding improvements. * rockchip,saradc - Add ID for rv1126. * semtech,sx9360 - Add SAMM0208 ACPI ID. Doesn't appear to be a valid vendor prefix but is in the wild. * st,lsm6dsx - Factor out common code as _device_set_enable(). - Fix up wrong docs after LSM6DSV addition. * st,stm32-adc - Manage the min sampling time on all internal channels. * trig,sysfs - Improve error labels. * tag 'iio-for-6.2a-take2' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (146 commits) iio: pressure: bmp280: convert to i2c's .probe_new() iio: imu: st_lsm6dsx: fix LSM6DSV sensor description iio: adc: ad4130: depend on GPIOLIB staging: iio: meter: replace ternary operator by if condition iio: light: apds9960: Fix iio_event_spec structures dt-bindings: iio: imu: Add inv_icm42600 documentation iio: imu: inv_icm42600: Add support for icm42631 dt-bindings: iio: adc: rockchip-saradc: Add saradc for rv1126 dt-bindings: iio: dac: adi,ad5758: Drop 'contains' from 'adi,dc-dc-mode' dt-bindings: iio: imu: st_lsm6dsx: add lsm6dsv16x iio: imu: st_lsm6dsx: add support to LSM6DSV16X iio: proximity: sx9360: Add a new ACPI hardware ID iio: temperature: mlx90632: Add missing static marking on devm_pm_ops iio: temperature: mlx90632: Add error handling for devm_pm_runtime_enable() iio: temperature: ltc2983: support more parts dt-bindings: iio: temperature: ltc2983: support more parts dt-bindings: iio: temperature: ltc2983: use generic node name in example dt-bindings: iio: temperature: ltc2983: describe broken mux delay property dt-bindings: iio: temperature: ltc2983: refine descriptions dt-bindings: iio: temperature: ltc2983: change default excitation for custom thermistors ...
