Subject: [PATCH v3 8/9] arm64: dts: st: add DMA support on I2C instances of stm32mp25
Date: Wed, 16 Oct 2024 14:40:00 +0200 [thread overview]
Message-ID: <20241016-dma3-mp25-updates-v3-8-8311fe6f228d@foss.st.com> (raw)
In-Reply-To: <20241016-dma3-mp25-updates-v3-0-8311fe6f228d@foss.st.com>
Add dmas and dma-names properties in i2c nodes of stm32mp251.dtsi to
enable DMA support.
