Subject: [PATCH 2/2] ARM: dts: stm32: add MDMA on STM32MP13x SoC family
Date: Tue, 1 Feb 2022 17:05:06 +0100 [thread overview]
Message-ID: <20220201160506.348701-3-amelie.delaunay@foss.st.com> (raw)
In-Reply-To: <20220201160506.348701-1-amelie.delaunay@foss.st.com>
MDMA on STM32MP13x SoCs is the same than on STM32MP15x SoCs: it offers up
to 32 channels and supports 48 requests.
