Subject: [PATCH net-next 05/10] ARM: dts: stm32: add pin map for CAN controller on stm32f4

From: Dario Binacchi <dario.binacchi@...rulasolutions.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).
