Merge tag 'char-misc-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char / misc / other smaller driver subsystem updates from Greg KH:
"Here is the large set of char, misc, and other driver subsystem
updates for 5.19-rc1. The merge request for this has been delayed as I
wanted to get lots of linux-next testing due to some late arrivals of
changes for the habannalabs driver.
Highlights of this merge are:
- habanalabs driver updates for new hardware types and fixes and
other updates
- IIO driver tree merge which includes loads of new IIO drivers and
cleanups and additions
- PHY driver tree merge with new drivers and small updates to
existing ones
- interconnect driver tree merge with fixes and updates
- soundwire driver tree merge with some small fixes
- coresight driver tree merge with small fixes and updates
- mhi bus driver tree merge with lots of updates and new device
support
- firmware driver updates
- fpga driver updates
- lkdtm driver updates (with a merge conflict, more on that below)
- extcon driver tree merge with small updates
- lots of other tiny driver updates and fixes and cleanups, full
details in the shortlog.
All of these have been in linux-next for almost 2 weeks with no
reported problems"
