Merge tag 'char-misc-7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-miscPull char/misc/IIO/etc driver updates from Greg KH: "Here is the big set of char, misc, iio, counter, fpga, and other small driver subsystems for 7.3-rc1. Overall, due to some driver removals we only added a bit more code than removed, which was a nice change. Highlights in this merge request are: - Loads of IIO driver updates and additions - binder driver updates (more on that below...) - Removal of the SGI XP and GRU drivers as they are not used anymore and turn out to be pretty insecure overall - Removal of the obsolete ibmasm driver as it's not being used anymore - Coresight driver updates and additions - Mei driver udpates - Counter driver updates - FPGA driver updates - ICC driver updates - lots and lots of other tiny driver updates to resolve reported issues All of these have been in linux-next for a while"* tag 'char-misc-7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (513 commits) iio: chemical: atlas-sensor: use iio_trigger_poll_nested() to fix remove UAF iio: adc: pac1921: fix wrong channel used in trigger handler read iio: light: gp2ap002: re-enable irq if runtime suspend fails iio: light: gp2ap002: Fix unbalanced runtime PM on repeated event writes iio: light: apds9306: fix PM reference leak in apds9306_read_data() iio: gyro: mpu3050: fix sign of raw angular velocity readings iio: srf04: fix pm_runtime handling on probe error path iio: adc: ad4080: configure backend data size iio: adc: adi-axi-adc: add data size support for AD408X backend iio: chemical: atlas-sensor: fix PM reference leak in buffer postenable iio: dac: ad5446: fix OF module device table iio: light: opt4001: Fix reversed GENMASK() arguments in fault count mask iio: light: opt4001: Reject integration times with a non-zero seconds part iio: light: opt4001: Fix incompatible pointer type passed to div_u64_rem() iio: light: opt4001: Fix power down clearing bits of the wrong register iio: light: opt4060: Fix incorrect register name in threshold read error message iio: light: opt4060: Fix pointer type passed to div_u64_rem() iio: light: opt4060: Reject integration times with a non-zero seconds part iio: light: ltrf216a: fix runtime PM reference leak in error path iio: pressure: dps310: fix NULL pointer dereference on ACPI probe ...

issei: implement main thread and ham messagesIntroduce the main thread and HECI Active Management (HAM)message handling for the ISSEI (Intel Silicon Security EngineInterface) subsystem.The main thread is responsible for managing the reset flow andprocessing messages, while the HAM message handling is crucialfor initializing communication with the firmware and managingclients.With this implementation, the ISSEI driver is capable of performingthe required initialization and management of communication betweenthe host and the firmware.Reviewed-by: Karol Wachowski Co-developed-by: Vitaly Lubart Signed-off-by: Vitaly Lubart Signed-off-by: Alexander Usyskin Link: https://patch.msgid.link/20260513-issei-for-upstream-v1-3-f590038678f9@intel.comSigned-off-by: Greg Kroah-Hartman List of files: /linux/drivers/misc/issei/issei_dev.h

issei: initial driver skeletonThe ISSEI (Intel Silicon Security Engine Interface)subsystem provides a communication channel between the host and theSilicon Security Engine.Prepare basic driver functions and character devicefor user-space communication.Add DMA access routines for ISSEI HECI devices.Add of DMA-related structures and implementation of routines forsetting up DMA, as well as reading and writing DMA buffers.Reviewed-by: Karol Wachowski Co-developed-by: Vitaly Lubart Signed-off-by: Vitaly Lubart Signed-off-by: Alexander Usyskin Link: https://patch.msgid.link/20260513-issei-for-upstream-v1-1-f590038678f9@intel.comSigned-off-by: Greg Kroah-Hartman List of files: /linux/drivers/misc/issei/issei_dev.h
