[ Upstream commit e2c77032fcbe515194107994d12cd72ddb77b022 ]
The macros for the unit conversion for frequency are duplicated in
different places.
Provide these macros in the 'units' header, so they can be reused.

[ Upstream commit c9221919a2d2df5741ab074dfec5bdfc6f1e043b ]
Patch series "Add Hz macros", v3.
There are multiple definitions of the HZ_PER_MHZ or HZ_PER_KHZ in the
different drivers. Instead of duplicating this definition again and
again, add one in the units.h header to be reused in all the place the
redefiniton occurs.
At the same time, change the type of the Watts, as they can not be
negative.
This patch (of 10):
The users of the macros are safe to be assigned with an unsigned instead
of signed as the variables using them are themselves unsigned.

As there are the temperature units, let's add the Watt macros definition.

[ Upstream commit 23331e4893614deb555c65cdf115c8a28ed32471 ]
Patch series "add header file for kelvin to/from Celsius conversion
helpers", v4.
There are several helper macros to convert kelvin to/from Celsius in
<linux/thermal.h> for thermal drivers. These are useful for any other
drivers or subsystems, but it's odd to include <linux/thermal.h> just
for the helpers.
This adds a new <linux/units.h> that provides the equivalent inline
functions for any drivers or subsystems, and switches all the users of
conversion helpers in <linux/thermal.h> to use <linux/units.h> helpers.
