Subject: [PATCH] ARM: dts: stm32: add resets property to m_can nodes in the stm32mp153
Date: Wed, 06 Aug 2025 10:59:12 +0200 [thread overview]
Message-ID: <20250806-stm32mp15-m_can-add-reset-v1-1-9d81f9c29d65@pengutronix.de> (raw)
On the STM32MP153 the m_cam IP cores (a.k.a. FDCAN) have an external
shared reset in the RCC. Add the reset to both m_can nodes.
