Add support for bxcan (Basic eXtended CAN controller) to STM32F429. The chip contains two CAN peripherals, CAN1 the primary and CAN2 the secondary, that share some of the required logic like clock and filters. This means that the secondary CAN can't be used without the primary CAN. Signed-off-by: Dario Binacchi <dario.binacchi@amarulasolutions.com> --- Changes in v9: - Replace master/slave terms with primary/secondary. Changes in v6: - move can1 node before gcan to keep ordering by address. Changes in v4: - Replace the node can@40006400 (compatible "st,stm32f4-bxcan-core") with the gcan@40006600 node ("sysnode" compatible). The gcan node contains clocks and memory addresses shared by the two can nodes of which it's no longer the parent. - Add to can nodes the "st,gcan" property (global can memory) which references the gcan@40006600 node ("sysnode compatibble). Changes in v3: - Remove 'Dario Binacchi <dariobin@libero.it>' SOB. - Add "clocks" to can@0 node. arch/arm/boot/dts/stm32f429.dtsi | 29 +++++++++++++++++++++++++++++ 1 file changed, 29 insertions(+)
