This adds the enable attribute which is used to select if zero PWM duty
means to switch off regulator and PWM or to keep them enabled but
at inactive PWM output level.
Depending on the select enable mode, turn off the regulator and PWM if
the PWM duty is zero, or keep them enabled.
This is especially important for fan using inverted PWM signal polarity.
Having regulator supplied and PWM disabled, some PWM controllers provide
the active, rather than inactive signal.
With this change the shutdown as well as suspend/resume paths require
modifcations as well.

The current equation used in code is aligned to series 5:
T = G + H * (n / cal5 - 0.5) + J * F
Where:
G = 60, H = 200, cal5 = 4094, J = -0.1, F = frequency clock in MHz
Series 6 has a slightly different equation:
T = G + H * (n / cal5 - 0.5)
and a different set of coefficients:
G = 57.4, H = 249.4, cal5 = 4096
This change supports equation and coefficients for both series.
(for series 6, J is set to 0).
The series is determined according to “moortec,ts-series” property in
the device tree.
If absent, series 5 is assumed to be the default.

Modify the equation and coefficients used to convert the digital output
to temperature according to series 5 of the Moortec Embedded Temperature
Sensor (METS) datasheet:
T = G + H * (n / cal5 - 0.5) + J * F
Where:
*) G = 60, H = 200, cal5 = 4094, J = -0.1.
*) F = frequency clock in MHz.
*) n is the digital output.
In code, the G, H and J coefficients are multiplied by a factor of 1000
to get the temperature in milli-Celsius.
Final result is clamped in case it exceeds min/max thresholds.
Change is done since it is unclear where the current equation and
coefficients came from.

The driver reads from the device-tree all the channels that use the

'val' is u8 and thus can never be larger than 255. In theory
the operation calculating 'val' could result in a value larger
than 255, but this won't happen because its parameter has already
been range checked and it is guaranteed that the result never exceeds
255. Remove the unnecessary value check.

Extend aquacomputer_d5next driver to expose various hardware
sensors of the Aquacomputer High Flow Next flow sensor, which
communicates through a proprietary USB HID protocol.
The High Flow Next exposes +5V voltages, water quality, conductivity
and flow readings. A temperature sensor can be connected to it, in
which case it provides its reading and an estimation of the
dissipated/absorbed power in the liquid cooling loop.
Additionally, serial number and firmware version are exposed through
debugfs.
Registry offsets were discovered and tested by users on Github [1] [2].

When reading the 'port_status' debugfs entry, some I2C registers were
read more than once. This looks inefficient in an I2C trace.
To reduce I2C traffic, update tps23861_port_status_show() to only read
each register once. Indexing the port number from 0 instead of 1 also
allows simplifying things a bit.

The MAX31790 has a tach input enable bit in each fan's configuration
register. This is only enabled by the driver if RPM mode is selected,
but the driver doesn't provide a way to independently enable tachometer
input regardless of the regulator mode.
By adding the fanN_enable sysfs files, we can decouple the tach input
from the regulator mode. Also update the documentation.
