Pull char / misc driver updates from Greg KH: "Here is the "big" set of char/misc and other driver subsystem changes for 6.12-rc1. Lots of changes in here, primarily dominated by the usual IIO driver updates and additions, but there are also small driver subsystem updates all over the place. Included in here are: - lots and lots of new IIO drivers and updates to existing ones - interconnect subsystem updates and new drivers - nvmem subsystem updates and new drivers - mhi driver updates - power supply subsystem updates - kobj_type const work for many different small subsystems - comedi driver fix - coresight subsystem and driver updates - fpga subsystem improvements - slimbus fixups - binder new feature addition for "frozen" notifications - lots and lots of other small driver updates and cleanups All of these have been in linux-next for a long time with no reported problems" * tag 'char-misc-6.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (354 commits) greybus: gb-beagleplay: Add firmware upload API arm64: dts: ti: k3-am625-beagleplay: Add bootloader-backdoor-gpios to cc1352p7 dt-bindings: net: ti,cc1352p7: Add bootloader-backdoor-gpios MAINTAINERS: Update path for U-Boot environment variables YAML nvmem: layouts: add U-Boot env layout comedi: ni_routing: tools: Check when the file could not be opened ocxl: Remove the unused declarations in headr file hpet: Fix the wrong format specifier uio: Constify struct kobj_type cxl: Constify struct kobj_type binder: modify the comment for binder_proc_unlock iio: adc: axp20x_adc: add support for AXP717 ADC dt-bindings: iio: adc: Add AXP717 compatible iio: adc: axp20x_adc: Add adc_en1 and adc_en2 to axp_data w1: ds2482: Drop explicit initialization of struct i2c_device_id::driver_data to 0 tools: iio: rm .*.cmd when make clean iio: adc: standardize on formatting for id match tables iio: proximity: aw96103: Add support for aw96103/aw96105 proximity sensor bus: mhi: host: pci_generic: Enable EDL trigger for Foxconn modems bus: mhi: host: pci_generic: Update EDL firmware path for Foxconn modems ...
