Subject: [PATCH v2 2/2] ARM: dts: stm32: add resets property to m_can nodes in the stm32mp153
Date: Thu, 07 Aug 2025 08:09:31 +0200 [thread overview]
Message-ID: <20250807-stm32mp15-m_can-add-reset-v2-2-f69ebbfced1f@pengutronix.de> (raw)
In-Reply-To: <20250807-stm32mp15-m_can-add-reset-v2-0-f69ebbfced1f@pengutronix.de>
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.
