Here is the big set of char/misc and other small driver subsystem updates for 5.18-rc1. Included in here are merges from driver subsystems which contain: - iio driver updates and new drivers - fsi driver updates - fpga driver updates - habanalabs driver updates and support for new hardware - soundwire driver updates and new drivers - phy driver updates and new drivers - coresight driver updates - icc driver updates Individual changes include: - mei driver updates - interconnect driver updates - new PECI driver subsystem added - vmci driver updates - lots of tiny misc/char driver updates There will be two merge conflicts with your tree, one in MAINTAINERS which is obvious to fix up, and one in drivers/phy/freescale/Kconfig which also should be easy to resolve. All of these have been in linux-next for a while with no reported problems.
