Subject: [PATCH v10 4/5] ARM: dts: stm32: add pin map for CAN controller on stm32f4
Date: Tue, 28 Mar 2023 09:33:27 +0200	[thread overview]
Message-ID: <20230328073328.3949796-5-dario.binacchi@amarulasolutions.com> (raw)
In-Reply-To: <20230328073328.3949796-1-dario.binacchi@amarulasolutions.com>

Add pin configurations for using CAN controller on stm32f469-disco
board. They are located on the Arduino compatible connector CN5 (CAN1)
and on the extension connector CN12 (CAN2).
