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 Host
--------

Support for new modems:

- Foxconn Cinterion MV32-WA/MV32-WB based on SDX62/SDX65
- Telit FN980 v1 based on SDX55
- Telit FN990 based on SDX65
- Foxconn T99W373/T99W368 based on SDX62/SDX65

Core changes:

- During the recycle of event ring elements, compute the ctxt_wp based on the
local cached value instead of reading from shared memory. This is to prevent
the possible corruption of the ctxt_wp as some of the endpoint devices could
modify the value in shared memory.

- Add sysfs support for resetting the endpoint based on the MHI spec. The MHI
spec allows the host to hard reset the device in the case of an unrecoverable
error and all other reset mechanisms have failed.

- During MHI shutdown, wait for the endpoint device to enter the ready state
post reset before proceeding. This is to avoid a possible race where host
would remove the interrupt handler and device will send ready state
interrupt, resulting in IOMMU fault.

- Bail out updating the MHI register if the read has failed during
read/modify/write.

- Use mhi_write_reg() instead of mhi_write_reg_field() for writing the whole
register fields in mhi_init_mmio().

MAINTAINERS change:

- Since Qualcomm has moved the email domain for its employess from codeaurora
domain to quicinc, update the same for Hemant.

bus: mhi: host: Add soc_reset sysfs

The MHI bus supports a standardized hardware reset, which is known as the
"SoC Reset". This reset is similar to the reset sysfs for PCI devices -
a hardware mechanism to reset the state back to square one.

The MHI SoC Reset is described in the spec as a reset of last resort. If
some unrecoverable error has occurred where other resets have failed, SoC
Reset is the "big hammer" that ungracefully resets the device. This is
effectivly the same as yanking the power on the device, and reapplying it.
However, depending on the nature of the particular issue, the underlying
transport link may remain active and configured. If the link remains up,
the device will flag a MHI system error early in the boot process after
the reset is executed, which allows the MHI bus to process a fatal error
event, and clean up appropiately.

While the SoC Reset is generally intended as a means of recovery when all
else has failed, it can be useful in non-error scenarios. For example,
if the device loads firmware from the host filesystem, the device may need
to be fully rebooted inorder to pick up the new firmware. In this
scenario, the system administrator may use the soc_reset sysfs to cause
the device to pick up the new firmware that the admin placed on the
filesystem.
