Merge tag 'char-misc-7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char/misc/IIO/etc driver updates from Greg KH:
"Here is the big set of char, misc, iio, counter, fpga, and other small
driver subsystems for 7.3-rc1.

Overall, due to some driver removals we only added a bit more code
than removed, which was a nice change. Highlights in this merge
request are:

- Loads of IIO driver updates and additions

- binder driver updates (more on that below...)

- Removal of the SGI XP and GRU drivers as they are not used anymore
and turn out to be pretty insecure overall

- Removal of the obsolete ibmasm driver as it's not being used
anymore

- Coresight driver updates and additions

- Mei driver udpates

- Counter driver updates

- FPGA driver updates

- ICC driver updates

- lots and lots of other tiny driver updates to resolve reported
issues

All of these have been in linux-next for a while"

issei: add firmware and host clients implementation, finish character device

Add the core implementation for firmware and host client
management within the ISSEI (Intel Silicon Security Engine Interface)
subsystem support for a character device to expose the ISSEI
HECI interface to user space.
The firmware client (fw_client) and host client (host_client) modules
are responsible for managing communication between the host software
and the firmware.
The character device provides a communication channel for user-space
applications to interact with the firmware on the platform.

The client modules enable the ISSEI driver to manage multiple
host clients communicating with corresponding firmware
clients, facilitating data transfers and control operations
over the HECI interface.
The character device allows user-space applications to establish
connections to firmware clients using UUIDs, exchange messages,
and control the communication flow using standard
file operation calls.
