Subject: [PATCH v3 2/2] arm: dts: stm32: remove useless clocksource nodes
Date: Wed, 20 Sep 2017 16:51:07 +0200 [thread overview]
Message-ID: <1505919067-28041-3-git-send-email-benjamin.gaignard@linaro.org> (raw)
In-Reply-To: <1505919067-28041-1-git-send-email-benjamin.gaignard@linaro.org>
16 bits timers aren't accurate enough to be used as
clocksource, remove them from stm32f4 and stm32f7 devicetree.
