Subject: [PATCH v3 9/9] arm64: dts: st: add i2c2 / i2c8 properties on stm32mp257f-ev1
Date: Fri, 15 Dec 2023 18:06:13 +0100 [thread overview]
Message-ID: <20231215170617.95868-10-alain.volmat@foss.st.com> (raw)
In-Reply-To: <20231215170617.95868-1-alain.volmat@foss.st.com>
Add properties for i2c2 and i2c8 available on the stm32mp257f-ev1.
i2c2 is enabled since several devices are attached to it while
i2c8 is kept disabled since only used via the gpio expansion connector.
Signed-off-by: Alain Volmat <alain.volmat@foss.st.com>
