HZ unit conversion macros are available in units.h, use them and remove
the duplicate definition.
The new macro is an unsigned long. The code dealing with it is
considering as an unsigned long also.

This driver exposes hardware sensors of the Aquacomputer D5 Next
watercooling pump, which communicates through a proprietary USB HID
protocol.
Available sensors are pump and fan speed, power, voltage and current, as
well as coolant temperature. Also available through debugfs are the serial
number, firmware version and power-on count.
Attaching a fan is optional and allows it to be controlled using
temperature curves directly from the pump. If it's not connected,
the fan-related sensors will report zeroes.
The pump can be configured either through software or via its physical
interface. Configuring the pump through this driver is not implemented,
as it seems to require sending it a complete configuration. That
includes addressable RGB LEDs, for which there is no standard sysfs
interface. Thus, that task is better suited for userspace tools.
This driver has been tested on x86_64, both in-kernel and as a module.

In the initial implementation a number of PMBUS_x_WARN_LIMITs were
mapped to MFR fields. This was incorrect as these MFR limits reflect the
rated limit as opposed to a limit which will generate warning. Instead
return -ENXIO like we were already doing for other WARN_LIMITs.
Subsequently these rated limits have been exposed generically as new
fields in the sysfs ABI so the values are still available.

The HW has some predefined points where it will associate a PWM value.
However some users might want to better set these points to their
usecases. This patch exposes these points as pwm auto_points:
* pwm1_auto_point1_temp_hyst: temperature threshold below which PWM should
be 0%;
* pwm1_auto_point1_temp: temperature threshold above which PWM should be
25%;
* pwm1_auto_point2_temp_hyst: temperature threshold below which PWM should
be 25%;
* pwm1_auto_point2_temp: temperature threshold above which PWM should be
50%;
* pwm1_auto_point3_temp_hyst: temperature threshold below which PWM should
be 50%;
* pwm1_auto_point3_temp: temperature threshold above which PWM should be
75%;
* pwm1_auto_point4_temp_hyst: temperature threshold below which PWM should
be 75%;
* pwm1_auto_point4_temp: temperature threshold above which PWM should be
100%;

The core will now start out of reset at boot as soon as clocking is
available. Hence, by the time we unmask the interrupts we already might
have some of them set. Thus, it's important to handle them in the
natural order the core generates them. Otherwise, we could process
'ADI_IRQ_SRC_PWM_CHANGED' before 'ADI_IRQ_SRC_TEMP_INCREASE' and
erroneously set 'update_tacho_params' to true.

On AMD platforms the Out-of-band access is provided by
Advanced Platform Management Link (APML), APML is a
SMBus v2.0 compatible 2-wire processor client interface.
APML is also referred as the sideband interface (SBI).
APML is used to communicate with the
Side-Band Remote Management Interface (SB-RMI) which provides
Soft Mailbox messages to manage power consumption and
power limits of the CPU socket.
- This module add support to read power consumption,
power limit & max power limit and write power limit.
- To instantiate this driver on a Board Management Controller (BMC)
connected to an AMD CPU with SB-RMI support, the i2c bus number
would be the bus connected from the BMC to the CPU.

init code and allows w83627ehf_probe() to be marked
as __init, lowering the runtime memory footprint.

The BPD-RS600 is the DC version of the BPA-RS600. The PMBUS interface is
the same between the two models. Keep the same compatible string but
accept either BPA-RS600 or BPD-RS600 in the PMBUS_MFR_MODEL.

The kernel has a helper function for linear interpolation so
use it. It incidentally makes the code easier to read as well.
Tested on the ST-Ericsson HREFv60plus hardware reference design
with two thermistors forming a thermal zone.

In order to better debug problems starting up the driver, print
the response status from the OCC in the error logged when the first
poll command fails.

Initialize the sequence number at one, rather than zero, in order
to prevent false matches with the zero-initialized OCC SRAM
buffer before the OCC is fully initialized.

Support set_trips() callback of thermal device ops. This allows HWMON
device to operatively notify thermal core about temperature changes, which
is very handy to have in a case where HWMON sensor is used by CPU thermal
zone that performs passive cooling and emergency shutdown on overheat.
Thermal core will be able to react faster to temperature changes.
The set_trips() callback is entirely optional. If HWMON sensor doesn't
support setting thermal trips, then the callback is a NO-OP. The dummy
callback has no effect on the thermal core. The temperature trips are
either complement the temperature polling mechanism of thermal core or
replace the polling if sensor can set the trips and polling is disabled
by a particular device in a device-tree.

The min/max/crit and all other temperature values that are passed to
the driver are unlimited and value that is close to INT_MIN results in
integer underflow of the temperature calculations made by the driver
for LM99 sensor. Temperature hysteresis is among those values that need
to be limited, but limiting of hysteresis is independent from the sensor
version. Add the missing limits.

I2C accesses are prohibited and will error out after suspending of the
I2C controller, hence we need to ensure that interrupt won't fire on
suspend when it's too late. Disable interrupt across suspend/resume.

The ALERT interrupt is enabled by default after power-on, but it could
be masked by bootloader. For example this is the case on Acer A500 tablet
device. Unmask the hardware interrupt if interrupt is provided.
