Add the missing CAN devices node including their pin muxing and clocks. Signed-off-by: Alexander Stein <redacted> --- I could actually only test CAN1 due to the hardware I had available. Also CAN0 conflicts with DBGU pins, which I had to use. arch/arm/boot/dts/at91sam9x5.dtsi | 48 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 48 insertions(+)diff --git a/arch/arm/boot/dts/at91sam9x5.dtsi b/arch/arm/boot/dts/at91sam9x5.dtsi index e1a5c70..0a2164e 100644 --- a/arch/arm/boot/dts/at91sam9x5.dtsi +++ b/arch/arm/boot/dts/at91sam9x5.dtsi@@ -763,6 +795,22 @@ }; }; + can0 { + pinctrl_can0_rx_tx: can0_rx_tx { + atmel,pins = + <AT91_PIOA 9 AT91_PERIPH_B AT91_PINCTRL_NONE /* PA9 periph B RX */ + AT91_PIOA 10 AT91_PERIPH_B AT91_PINCTRL_NONE>; /* PA10 periph B TX */
I would stop adding that comment as this is pretty clear that your are setting PA9 and P10 to periph B. A more useful kind of comment is what pin it conflicts with. Maybe something like: <AT91_PIOA 9 AT91_PERIPH_B AT91_PINCTRL_NONE /* CANRX0, conflicts with DRXD */
