Subject: [PATCH v6 5/5] arm: dts: stm32: remove useless clocksource nodes
Date: Wed, 18 Oct 2017 14:58:26 +0200 [thread overview]
Message-ID: <1508331506-23782-6-git-send-email-benjamin.gaignard@linaro.org> (raw)
In-Reply-To: <1508331506-23782-1-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.
