Pull char / misc / IIO driver updates from Greg KH: "Here is the big set of char, misc, iio, and other smaller driver subsystems for 6.15-rc1. Lots of stuff in here, including: - loads of IIO changes and driver updates - counter driver updates - w1 driver updates - faux conversions for some drivers that were abusing the platform bus interface - coresight driver updates - rust miscdevice binding updates based on real-world-use - other minor driver updates All of these have been in linux-next with no reported issues for quite a while" * tag 'char-misc-6.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (292 commits) samples: rust_misc_device: fix markup in top-level docs Coresight: Fix a NULL vs IS_ERR() bug in probe misc: lis3lv02d: convert to use faux_device tlclk: convert to use faux_device regulator: dummy: convert to use the faux device interface bus: mhi: host: Fix race between unprepare and queue_buf coresight: configfs: Constify struct config_item_type doc: iio: ad7380: describe offload support iio: ad7380: add support for SPI offload iio: light: Add check for array bounds in veml6075_read_int_time_ms iio: adc: ti-ads7924 Drop unnecessary function parameters staging: iio: ad9834: Use devm_regulator_get_enable() staging: iio: ad9832: Use devm_regulator_get_enable() iio: gyro: bmg160_spi: add of_match_table dt-bindings: iio: adc: Add i.MX94 and i.MX95 support iio: adc: ad7768-1: remove unnecessary locking Documentation: ABI: add wideband filter type to sysfs-bus-iio iio: adc: ad7768-1: set MOSI idle state to prevent accidental reset iio: adc: ad7768-1: Fix conversion result sign iio: adc: ad7124: Benefit of dev = indio_dev->dev.parent in ad7124_parse_channel_config() ...

The above command enables two events: one is the event *cycles* from PMU
