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" * tag 'char-misc-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (387 commits) habanalabs: use separate structure info for each error collect data habanalabs: fix missing handle shift during mmap habanalabs: remove hdev from hl_ctx_get args habanalabs: do MMU prefetch as deferred work habanalabs: order memory manager messages habanalabs: return -EFAULT on copy_to_user error habanalabs: use NULL for eventfd habanalabs: update firmware header habanalabs: add support for notification via eventfd habanalabs: add topic to memory manager buffer habanalabs: handle race in driver fini habanalabs: add device memory scrub ability through debugfs habanalabs: use unified memory manager for CB flow habanalabs: unified memory manager new code for CB flow habanalabs/gaudi: set arbitration timeout to a high value habanalabs: add put by handle method to memory manager habanalabs: hide memory manager page shift habanalabs: Add separate poll interval value for protocol habanalabs: use get_task_pid() to take PID habanalabs: add prefetch flag to the MAP operation ...
