Merge tag 'char-misc-6.3-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 large set of driver changes for char/misc drivers and
other smaller driver subsystems that flow through this git tree.
Included in here are:
- New IIO drivers and features and improvments in that subsystem
- New hwtracing drivers and additions to that subsystem
- lots of interconnect changes and new drivers as that subsystem
seems under very active development recently. This required also
merging in the icc subsystem changes through this tree.
- FPGA driver updates
- counter subsystem and driver updates
- MHI driver updates
- nvmem driver updates
- documentation updates
- Other smaller driver updates and fixes, full details in the
shortlog
All of these have been in linux-next for a while with no reported
problems"
