[ 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.
