Problem:
We use voltage dividers so that the voltage presented at the voltage

meaningful readings given the voltage divider.
Solution:
Read the voltage divider resistance from dts and convert the voltage

If the PVT sensor is suddenly powered down while a caller is waiting for
the conversion completion, the request won't be finished and the task will
hang up on this procedure until the power is back up again. Let's call the
wait_for_completion_timeout() method instead to prevent that. The cached
timeout is exactly what we need to predict for how long conversion could
normally last.

Baikal-T1 PVT sensor has got a dedicated power supply domain (feed up by
the external GPVT/VPVT_18 pins). In case if it isn't powered up, the
registers will be accessible, but the sensor conversion just won't happen.
Due to that an attempt to read data from any PVT sensor will cause the
task hanging up. For instance that will happen if XP11 jumper isn't
installed on the Baikal-T1-based BFK3.1 board. Let's at least test whether
the conversion work on the device probe procedure. By doing so will make
sure that the PVT sensor is powered up at least at boot time.

While that is technically true, it won't be hit in the field since the
condition indicates a programming error. Move the check of that condition
into the code generating the attribute entry, and refuse generating the
attribute if the condition is true. Swap the condition check in
pmbus_get_boolean() to ensure that static analyzers don't get a hiccup

Caching register values can be very expensive for PMBus chips. Some
modern chips may have 10 or more pages, with several sensors supported
per page. For example, MAX16601 creates more than 90 sysfs attributes.
Register caching for such chips is time consuming, especially if only a
few attributes are read on a regular basis. For MAX16601, it was observed
that it can take up to two seconds to read all attributes on a slow I2C
bus. In this situation, register caching results in the opposite of its
intention: It increases the number of I2C operations, in some cases
substantially, and it results in large latency when trying to access
individual sensor data.
Drop all register caching to solve the problem. Since it is no longer
necessary, drop status register mapping as part of the change, and specify
status registers directly.

since register locations change too much between AMD chip revisions,
and the data isn't really valuable for chips where it isn't already
supported. On top of that, its existence has been used as argument
for providing pseudo-API debugfs functions in other drivers.

Use the nvmem kernel api to expose the black box
chip functionality to userspace.
Using this feature, the device is capable of recording
to nonvolatile flash memory the vital data about the
system status that caused the system to perform a
black box write.
A blackbox is 64 bytes of data containing all the
status registers, last two states of the sequencer,
timestamp and counters. The mapping of this data is
described in the adm1266 datasheet.
On power-up the driver sets the unix time to
the adm1266 using the SET_RTC command. This value
is incremented by an internal clock and it is used
as timestamp for the black box feature.

Many hwmon drivers don't use the id information provided by the old
i2c probe function, and the remainder can easily be adapted to the new
form ("probe_new") by calling i2c_match_id explicitly.
This avoids scanning the identifier tables during probes.
Drivers which didn't use the id are converted as-is; drivers which did
are modified to call i2c_match_id() with the same level of
error-handling (if any) as before.
This patch wraps up the transition for hwmon, with four stragglers not
included in the previous large patch.

This driver doesn't use the id information provided by the old i2c
probe function, so it can trivially be converted to the simple
("probe_new") form.

Many hwmon drivers don't use the id information provided by the old
i2c probe function, and the remainder can easily be adapted to the new
form ("probe_new") by calling i2c_match_id explicitly.
This avoids scanning the identifier tables during probes.
Drivers which didn't use the id are converted as-is; drivers which did
are modified as follows:
* if the information in i2c_client is sufficient, that's used instead
(client->name);
* anything else is handled by calling i2c_match_id() with the same
level of error-handling (if any) as before.
A few drivers aren't included in this patch because they have a
different set of maintainers. They will be covered by other patches.
