Subject: [PATCH v3 02/10] units: Add the HZ macros
Date: Mon, 16 Aug 2021 13:47:24 +0200	[thread overview]
Message-ID: <20210816114732.1834145-3-daniel.lezcano@linaro.org> (raw)
In-Reply-To: <20210816114732.1834145-1-daniel.lezcano@linaro.org>

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.
