Ok pour la serie -----Original Message----- From: Alain VOLMAT <alain.volmat@st.com> Sent: jeudi 23 janvier 2020 17:13 To: wsa@the-dreams.de; robh+dt@kernel.org Cc: mark.rutland@arm.com; Pierre Yves MORDRET <pierre-yves.mordret@st.com>; mcoquelin.stm32@gmail.com; Alexandre TORGUE <alexandre.torgue@st.com>; linux-i2c@vger.kernel.org; devicetree@vger.kernel.org; linux-stm32@st-md-mailman.stormreply.com; linux-arm-kernel@lists.infradead.org; linux-kernel@vger.kernel.org; Fabrice GASNIER <fabrice.gasnier@st.com>; Alain VOLMAT <alain.volmat@st.com> Subject: [PATCH 5/5] ARM: dts: stm32: add Fast Mode Plus info in I2C nodes of stm32mp151 Add the syscfg-fmp property in each i2c node in order to allow Fast Mode Plus speed if clock-frequency >= 1MHz is indicated.
