[PATCH v5 2/7] units: complement the set of Hz units

From: Dmitry Rokosov
Date: Fri Aug 12 2022 - 12:53:17 EST


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.
