Here is the big set of char/misc and other small driver subsystem
 changes for 6.6-rc1.
 
 Stuff all over the place here, lots of driver updates and changes and
 new additions.  Short summary is:
   - new IIO drivers and updates
   - Interconnect driver updates
   - fpga driver updates and additions
   - fsi driver updates
   - mei driver updates
   - coresight driver updates
   - nvmem driver updates
   - counter driver updates
   - lots of smaller misc and char driver updates and additions
 
 All of these have been in linux-next for a long time with no reported
 problems.

e7593bda6a hwmon: pmbus: Fix -EIO seen on pli1209
After doing performance optimizations the pli1209 driver failed to
probe with a probabilty of 2%. It wasn't able to read the PMBUS_OPERATION
register due to an -EIO error.

An investigation showed that the PLI1209 takes 230 usec to execute the
CLEAR_FAULTS command. During that time it's busy and NACKs all requests
on the SMBUS interface. It also NACKs reads on PMBUS_STATUS_BYTE
making it impossible to poll the BUSY flag.

Add a custom write_data function to just wait for not BUSY unconditionally
after sending a CLEAR_FAULTS command.

TEST: Verified using an I2C bus analyser that no more NACKs are seen after
      sending a CLEAR_FAULTS command.

The pmbus_check_byte_register function already calls clear
fault page, so there's no need to do it again in
pmbus_identify_common.

      one clear fault page is being send instead of two in a row.

14cf45f2f2 hwmon: pmbus: Reduce clear fault page invocations
Observing I2C traffic revealed consecutive transmission of CLEAR_FAULT
commands. While this doesn't cause issues, it extends driver probe time.

Avoid invoking pmbus_clear_fault_page for virtual registers, as they're
managed by the driver, not the chip.

TEST: Verified using an I2C bus analyzer that only one CLEAR_FAULT
      command is send instead 5 in a row.

311cb3638e hwmon: (hp-wmi-sensors) Initialize pevents in hp_wmi_sensors_init()
The following warning is given by the Smatch static checker:

  drivers/hwmon/hp-wmi-sensors.c:1937 hp_wmi_sensors_init()
  error: uninitialized symbol 'pevents'.

If there are no instances of the HPBIOS_PlatformEvents WMI object
available, init_platform_events() never initializes this pointer,
which may then be passed to hp_wmi_debugfs_init() uninitialized.

The impact should be limited because hp_wmi_debugfs_init() uses this
pointer only if the count of HPBIOS_PlatformEvents instances is _not_
zero, while conversely, it will be uninitialized only if the count of
such instances _is_ zero. However, passing it uninitialized still
constitutes a bug.

Add support for MP2971 and MP2973, the successor of MP2975.

The major differences are:
 - On MP2973 and MP2971 the Vref cannot be read and thus most of
   the OVP/current calculations won't work.
 - MP2973 and MP2971 also support LINEAR format for VOUT
 - MP2973 and MP2971 do not support OVP2
 - On MP2973 and MP2971 most registers are in LINEAR format
 - The IMVP9_EN bit has a different position
 - Per phase current sense haven't been implemented.

As on MP2975 most of the FAULT_LIMIT and WARN_LIMIT registers
have been redefined and doesn't provide the functionality as
defined in PMBUS spec.

Tested on MP2973 and MP2971.

In order to upstream MP2973/MP2971 simplify the code by removing support
for various VOUT formats. The MP2973 and MP2971 supports all PMBUS
supported formats for VOUT, while the MP2975 only support DIRECT and
VID for VOUT.

In DIRECT mode all chips report the voltage in 1mV/LSB.

Configure the chip to use DIRECT format for VOUT and drop the code
conversion code for other formats. The to be added chips MP2973/MP2971
will be configured to also report VOUT in DIRECT format.

The maximum voltage that can be reported in DIRECT format is 32768mV.
This is sufficient as the maximum output voltage for VR12/VR13 is

Testing note:
* Tested on nct6799 with IN/FAN/TEMP, and changing min/max/high/hyst,
  that triggers the corresponding alarms correctly. Good confirmation
  on the original mapping of the registers and masks.
  As to be expected, only 4 fans and 2 temps (fixed) have limits
