Subject: [PATCH 1/2] units: Add the HZ_PER_KHZ macro
Date: Tue, 23 Feb 2021 21:30:01 +0100 [thread overview]
Message-ID: <20210223203004.7219-1-daniel.lezcano@linaro.org> (raw)
The macro for the unit conversion for frequency is duplicated in
different places.
Provide this macro in the 'units' header, so it can be reused.
