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"

MHI support 3 types of rings:

1. Transfer ring
2. Event ring
3. Command ring

All rings reside inside the host memory and the MHI EP device maps it to
the device memory using blocks like PCIe iATU. The mapping is handled in
the MHI EP controller driver itself.

bus: mhi: ep: Add support for registering MHI endpoint controllers

This commit adds support for registering MHI endpoint controller drivers
with the MHI endpoint stack. MHI endpoint controller drivers manage
the interaction with the host machines (such as x86). They are also the
MHI endpoint bus master in charge of managing the physical link between
the host and endpoint device. Eventhough the MHI spec is bus agnostic,
the current implementation is entirely based on PCIe bus.

The endpoint controller driver encloses all information about the
underlying physical bus like PCIe. The registration process involves
parsing the channel configuration and allocating an MHI EP device.

Channels used in the endpoint stack follows the perspective of the MHI
host stack. i.e.,

UL - From host to endpoint
DL - From endpoint to host
