Pull char / misc driver updates from Greg KH:
"Here is the large set of char and misc and other driver subsystem
changes for 6.0-rc1.
Highlights include:
- large set of IIO driver updates, additions, and cleanups
- new habanalabs device support added (loads of register maps much
like GPUs have)
- soundwire driver updates
- phy driver updates
- slimbus driver updates
- tiny virt driver fixes and updates
- misc driver fixes and updates
- interconnect driver updates
- hwtracing driver updates
- fpga driver updates
- extcon driver updates
- firmware driver updates
- counter driver update
- mhi driver fixes and updates
- binder driver fixes and updates
- speakup driver fixes
All of these have been in linux-next for a while without any reported
problems"
