wifi: cfg80211: Add KHZ_PER_GHZ to units.h and reuse

2024-02-21T14:19:03+00:00

The KHZ_PER_GHZ might be used by others (with the name aligned
with similar constants). Define it in units.h and convert
wireless to use it.

There is going to be a new user of the BYTES_PER_[K/M/G]BIT definition
besides possibly existing ones. Add them to the header.

units: complement the set of Hz units

2022-08-28T15:52:28+00:00

Currently, Hz units do not have milli, micro and nano Hz coefficients.
Some drivers (IIO especially) use their analogues to calculate
appropriate Hz values. This patch includes them to units.h definitions,
so they can be used from different kernel places.

units: add the HZ macros

2021-09-08T18:50:25+00:00

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.

units: change from 'L' to 'UL'

2021-09-08T18:50:25+00:00

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.
