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
3040 mV.

* Increase available bits, IN: 16 to 24, FAN: 8 to 12,
TEMP: 6 to 12
* Reorder alarm/beep definitions to match in order to allow
additional inputs in the future
* Remove comments about 'unused' bits as probe() is a better
reference
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
currently on nct6799 on my board.
* Trouble with testing intrusion alarms and beeps, no way to confirm
those. As I understand now, intrusion/caseopen is probably not
connected on my board.
And I haven't seen a buzzer on a board in ages.

SMM665 and related chips are power controller/sequencer chips from
Summit Microelectronics. The company was acquired by Qualcomm in 2012,
and support for the chip series stopped.
The chips are long since gone from active use, making the driver
unsupportable and just consuming space and compile time. Remove it.

nct6799d-r and nct6796d-s are very similar and chip_id is only
different in the version nibblet.
Since both will be detected by the driver anyway due to the

strlcpy() reads the entire source buffer first.
This read may exceed the destination size limit.
This is both inefficient and can lead to linear read
overflows if a source string is not NUL-terminated [1].
In an effort to remove strlcpy() completely [2], replace
strlcpy() here with direct assignment.
strlcpy in this file is used to copy fixed-length strings which can be
completely avoided by direct assignment and is safe to do so. strlen()
is used to return the length of @tbuf.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

Add a 200ms delay after sending a ctrl report to Quadro,
Octo, D5 Next and Aquaero to give them enough time to
process the request and save the data to memory. Otherwise,
under heavier userspace loads where multiple sysfs entries
are usually set in quick succession, a new ctrl report could
be requested from the device while it's still processing the
previous one and fail with -EPIPE. The delay is only applied
if two ctrl report operations are near each other in time.
Reported by a user on Github [1] and tested by both of us.

Industrial processor i3255 supports temperatures -40 deg celcius
to 105 deg Celcius. The current implementation of k10temp_read_temp
rounds off any negative temperatures to '0'. To fix this,
the following changes have been made.
A flag 'disp_negative' is added to struct k10temp_data to support
AMD i3255 processors. Flag 'disp_negative' is set if 3255 processor
is found during k10temp_probe. Flag 'disp_negative' is used to
determine whether to round off negative temperatures to '0' in
k10temp_read_temp.

use the probe callback with the same prototype.

The series 2022/2023 reports slightly longer vendor/product strings
and shares USB ids. Technically the reply size is the USB HID packet
size (64 bytes) but all the supported commands do not use more than 8
bytes and replies reporting back strings do not use more then 24 bytes
(vendor and product are in one string in the newer devices now). The
rest of the reply is always filled with '\0'. Also update comments
and documentation accordingly.

According to ADI, changing PMON_CONFIG while the ADC is running can have
unexpected results. ADI recommends halting the ADC with PMON_CONTROL
before setting PMON_CONFIG and then resume after. Follow ADI
recommendation and disable ADC while PMON_CONFIG is updated.

According to ADI, changing PMON_CONFIG while ADC is running can have
unexpected results. ADI recommends halting the ADC with PMON_CONTROL
before setting PMON_CONFIG and then resume after.
To prepare for this change, rename adm1275_read_pmon_config()
and adm1275_write_pmon_config() to adm1275_read_samples() and
adm1275_write_samples() to more accurately reflect the functionality
of the code. Introduce new function adm1275_write_pmon_config()
and use it for all code writing into the PMON_CONFIG register.

NCT6799D is mostly compatible to NCT6798D, with minor variations.
Note that NCT6798D and NCT6799D have a new means to select temperature
sources, and to report temperatures from those sources. This is not
currently implemented, meaning that most likely not all temperatures
are reported.

OneXPlayer boards from the last generation (both for OneXPlayer and AOK
ZOE brands) have a toggle in the EC to switch the "Turbo/Silent" button
into a different keyboard event.
Add a means to use that "Turbo button takeover" function and expose it
to userspace in a custom sysfs `tt_toggle` attribute. It can be read to
take the current state. Write 1|0 to activate the function. The specific
keycode is dependent on the board but can be checked by running
`evtest` utility.
Newer BIOS on the OneXPlayer added this function aside from string changes.
Add a board enum to differentiate it from the old OneXplayer Mini AMD BIOS.
Currently known supported boards:
- AOK ZOE A1
- OneXPlayer Mini AMD (only newer BIOS version supported)
- OneXPlayer Mini Pro

Add support for medium repeatability.
Per datasheet:
The stated repeatability is 3 times the standard deviation (3σ)
of multiple consecutive measurements at the stated repeatability
and at constant ambient conditions. It is a measure for the noise
on the physical sensor output. Different measurement modes allow
for high/medium/low repeatability.
For the humidity sensor, repeatability is documented as
0.25% RH for low repeatability, 0.15% RH for medium repeatability,
and 0.10% RH for high repeatability. Support all three modes.
