Subject: [PATCH] ARM: dts: stm32: Enable high resolution timer
Date:   Fri, 27 Sep 2019 10:48:19 +0200
Message-ID: <20190927084819.645-1-benjamin.gaignard@st.com>

Precedence: bulk

Adding always-on makes arm arch_timer claim to be an high resolution timer.
That is possible because power mode won't stop clocking the timer.
