Merge tag 'char-misc-6.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc and other driver subsystem updates from Greg KH: "Here is the big set of char/misc and other driver subsystem updates for 6.10-rc1. Nothing major here, just lots of new drivers and updates for apis and new hardware types. Included in here are: - big IIO driver updates with more devices and drivers added - fpga driver updates - hyper-v driver updates - uio_pruss driver removal, no one uses it, other drivers control the same hardware now - binder minor updates - mhi driver updates - excon driver updates - counter driver updates - accessability driver updates - coresight driver updates - other hwtracing driver updates - nvmem driver updates - slimbus driver updates - spmi driver updates - other smaller misc and char driver updates All of these have been in linux-next for a while with no reported issues" * tag 'char-misc-6.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (319 commits) misc: ntsync: mark driver as "broken" to prevent from building spmi: pmic-arb: Add multi bus support spmi: pmic-arb: Register controller for bus instead of arbiter spmi: pmic-arb: Make core resources acquiring a version operation spmi: pmic-arb: Make the APID init a version operation spmi: pmic-arb: Fix some compile warnings about members not being described dt-bindings: spmi: Deprecate qcom,bus-id dt-bindings: spmi: Add X1E80100 SPMI PMIC ARB schema spmi: pmic-arb: Replace three IS_ERR() calls by null pointer checks in spmi_pmic_arb_probe() spmi: hisi-spmi-controller: Do not override device identifier dt-bindings: spmi: hisilicon,hisi-spmi-controller: clean up example dt-bindings: spmi: hisilicon,hisi-spmi-controller: fix binding references spmi: make spmi_bus_type const extcon: adc-jack: Document missing struct members extcon: realtek: Remove unused of_gpio.h extcon: usbc-cros-ec: Convert to platform remove callback returning void extcon: usb-gpio: Convert to platform remove callback returning void extcon: max77843: Convert to platform remove callback returning void extcon: max3355: Convert to platform remove callback returning void extcon: intel-mrfld: Convert to platform remove callback returning void ...
