Add support for the Congatec Board Controller. This controller exposes
temperature, voltage, current and fan sensors.
The available sensors list cannot be predicted. Some sensors can be

The driver has an internal list of all possible sensors, for all Congatec

their status (active or not).

Add initial support for the Texas Instruments TPS25990 eFuse.
This adds the basic PMBUS telemetry support for the device.
From Karol Przybylski:
The tps25990_read_word_data function contains a block of unreachable code
caused by the syntactic structure in the PMBUS_VIRT_READ_IIN_MAX case.
Specifically, the return TPS25990_READ_IIN_PEAK; statement immediately
exits the function, making the next lines unreachable.
This patch removes the return statement, leaving the expected handling.

Writing PMBus protected registers does succeed from the smbus perspective,
even if the write is ignored by the device and a communication fault is
raised. This fault will silently be caught and cleared by pmbus irq if one
has been registered.
This means that the regulator call may return succeed although the
operation was ignored.
With this change, the operation which are not supported will be properly
flagged as such and the regulator framework won't even try to execute them.

register) value is already used to read the current.

While the chips supported by this driver do not directly support current
limits, they do support setting shunt voltage limits. The shunt voltage
divided by the shunt resistor value is the current. On top of that,
calibration values are set such that in the shunt voltage register and
the current register report the same values. That means we can report and
configure current limits based on shunt voltage limits, and we can do so
with much better accuracy than by setting shunt voltage limits.

- Constified struct regmap_config where feasible
- Cleaned up amc6821 driver, and converted to use regmap and
with_info API
- Converted max6639 driver to use with_info API; added support for
additional sysfs attributes
- Fixed various sysfs attribute underflows
- Added PEC support to hwmon core, and use in lm90 and max31827
drivers
And various other minor fixes and improvements"

AMC6821 supports configuring if a fan is DC or PWM controlled.
Add support for the pwm1_mode attribute to make it runtime configurable.

After setting fan1_target and setting pwm1_enable to 4,
the fan controller tries to achieve the requested fan speed.

The chip does not have a fan divisor. What it does have is a configuration
to set either 2 or 4 pulses per fan rotation. Rename the attribute to
reflect its use. Update documentation accordingly.
