Subject: [PATCHv3 RESEND 5/8] ARM: dts: stm32: enable RTC on stm32f429-disco
Date: Mon, 16 Jan 2017 14:29:46 +0100 [thread overview]
Message-ID: <1484573388-590-3-git-send-email-amelie.delaunay@st.com> (raw)
In-Reply-To: <1484573388-590-1-git-send-email-amelie.delaunay@st.com>
This patch enables RTC on stm32f429-disco with LSI as clock source because
X2 crystal for LSE is not fitted by default.
