Subject: [PATCH 5/5] ARM: dts: stm32: add Fast Mode Plus info in I2C nodes of stm32mp151
Date: Thu, 23 Jan 2020 17:12:50 +0100	[thread overview]
Message-ID: <1579795970-22319-6-git-send-email-alain.volmat@st.com> (raw)
In-Reply-To: <1579795970-22319-1-git-send-email-alain.volmat@st.com>

Add the syscfg-fmp property in each i2c node in order to allow
Fast Mode Plus speed if clock-frequency >= 1MHz is indicated.
