Subject: [PATCH 4/4] ARM: dts: stm32: Add romem and temperature calibration on stm32mp157c
Date: Wed, 30 Jan 2019 17:38:56 +0100 [thread overview]
Message-ID: <1548866336-14765-5-git-send-email-fabrice.gasnier@st.com> (raw)
In-Reply-To: <1548866336-14765-1-git-send-email-fabrice.gasnier@st.com>
Add & enable stm32 factory-programmed memory. Describe temperature sensor
calibration cells. Non-volatile calibration data is made available by
stm32mp157c bootrom in bsec_dataX registers.
