Subject: [PATCH v2 3/7] dt-bindings: i2c: document st,stm32mp25-i2c compatible
Date: Fri, 8 Dec 2023 17:47:12 +0100 [thread overview]
Message-ID: <20231208164719.3584028-4-alain.volmat@foss.st.com> (raw)
In-Reply-To: <20231208164719.3584028-1-alain.volmat@foss.st.com>
Add a new compatible st,stm32mp25-i2c for the STM32MP25 series which
has only one interrupt line for both events and errors and differs in
term of handling of FastModePlus.
