…el/git/jic23/iio into char-misc-next Jonathan writes: IIO: 2nd set of new device support, cleanups and features for 6.9 New device support ================= adi,hmc425a - Add support for LTC6373 Instrumentation Amplifier. microchip,pac1934 - New driver supporting PAC1931, PAC1932, PAC1933 and PAC1934 power monitoring chips with accumulators. voltafield,af8133j - New driver for the AF8133J 3 axis magnetometer. Docs ==== New general documentation of device buffers, and a specific section on the adi,adis16475 IMU Features ======== kionix,kxcjk-1013 - Add support for ACPI ROTM (Microsoft defined ACPI method) to get rotation matrix. ti,tmp117 - Add missing vcc-supply control and binding. Cleanups and minor fixes ======================== Tree-wide - Corrected headers to remove linux/of.h from a bunch of drivers that only had it to get to linux/mod_devicetable.h - dt binding cleanup to drop redundant type from label properties. adi,hmc425a - Fix constraints on GPIO array sizes for different devices. adi,ltc2983 - Use spi_get_device_match_data instead of open coding similar. - Update naming of fw parsing function to reflect that it is not longer dt only. - Set the chip name explicitly to reduce fragility resulting from different entries in the various ID tables. bosch,bmg160 - Add spi-max-frequency property and limit to dt-binding. microchip,mcp320x - Use devm_* to simplify device removal and error handling. nxp,imx93 - Drop a non existent 4th interrupt from bindings. qcom,mp8xxx-xoadc - Drop unused kerneldoc renesas,isl29501 - Actually use the of_match table. rockchip,saradc - Fix channel bitmask - Fix write masks - Replace custom handling of optional reset control with how it should be done. ti,ads1298 - Fix error code to not return a successfully obtained regulator. - Avoid a divide by zero when setting frequency. ti,hdc2010 - Add missing interrupts dt binding property vishay,veml6075 - Make vdd-supply required in the dt-binding. * tag 'iio-for-6.9b' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (42 commits) dt-bindings: iio: gyroscope: bosch,bmg160: add spi-max-frequency dt-bindings: iio: adc: imx93: drop the 4th interrupt iio: proximity: isl29501: make use of of_device_id table iio: adc: qcom-pm8xxx-xoadc: drop unused kerneldoc struct pm8xxx_chan_info member dt-bindings: iio: adc: drop redundant type from label dt-bindings: iio: ti,tmp117: add optional label property MAINTAINERS: Add an entry for AF8133J driver iio: magnetometer: add a driver for Voltafield AF8133J magnetometer dt-bindings: iio: magnetometer: Add Voltafield AF8133J dt-bindings: vendor-prefix: Add prefix for Voltafield iio: adc: rockchip_saradc: replace custom logic with devm_reset_control_get_optional_exclusive iio: adc: rockchip_saradc: use mask for write_enable bitfield iio: adc: rockchip_saradc: fix bitmask for channels on SARADCv2 dt-bindings: iio: light: vishay,veml6075: make vdd-supply required iio: adc: adding support for PAC193x dt-bindings: iio: adc: adding support for PAC193X iio: temperature: ltc2983: explicitly set the name in chip_info iio: temperature: ltc2983: rename ltc2983_parse_dt() iio: temperature: ltc2983: make use of spi_get_device_match_data() iio: adc: ti-ads1298: prevent divide by zero in ads1298_set_samp_freq() ...

| Description: | ||
| The value of the shunt resistor may be known only at runtime | ||
| and set by a client application. This attribute allows to | ||
| set its value in micro-ohms. X is the IIO index of the device. | ||
| Y is the channel number. The value is used to calculate | ||
| current, power and accumulated energy. |

| description: | ||
| A GPIO used to trigger a change is sampling rate (lowering the chip power | ||
| consumption). If configured in SLOW mode, if this pin is forced high, | ||
| sampling rate is forced to eight samples/second. When it is forced low, | ||
| the sampling rate is 1024 samples/second unless a different sample rate | ||
| has been programmed. | ||
