Tcan 4550 SPI device tree help

Hello,

I'm trying to add tcan4550 to my microchip sama5d27 board, and it's seem that I have a mistake on the device tree config:

spi1: spi@fc000000 {

pinctrl-names = "default";

pinctrl-0 = <&pinctrl_spi1_default>;

status = "okay";

spidev@0 {

compatible = "spidev";

spi-max-frequency = <10000000>;

reg = <0>;

};

tcan4x5x: can@0 {

//Device_Tree: https://docs.zephyrproject.org/latest/build/dts/api/bindings/can/ti,tcan4x5x.html

//Driver: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/net/can/m_can

compatible = "ti,tcan4x5x";

reg = <0>;

// #address-cells = <1>;

// #size-cells = <1>;

spi-max-frequency = <18000000>;

clock-frequency = <40000000>;

device-state-gpios = <PIN_PA16 GPIO_ACTIVE_HIGH>;

// device-wake-gpios = <&gpio0 1 GPIO_ACTIVE_HIGH>;

// reset-gpios = <&gpio0 2 GPIO_ACTIVE_HIGH>;

// int-gpios = <&gpio0 3 GPIO_ACTIVE_LOW>;

bosch,mram-cfg = <0x0 15 15 5 5 0 10 10>;

bus-speed = <250000>;

bus-speed-data = <1000000>;

status = "okay";

can-transceiver {

max-bitrate = <8000000>;

};

I can see that spi0.0 has been created , but not tcan interface

this is the dmesg error:

"dmesg | grep "spi0"
spi_master spi0: spi_device register error /ahb/apb/spi@fc000000/can@0
spi_master spi0: Failed to create SPI device for /ahb/apb/spi@fc000000/can@0

cat /sys/bus/spi/devices/spi0.0/uevent
OF_NAME=spidev
OF_FULLNAME=/ahb/apb/spi@fc000000/spidev@0
OF_COMPATIBLE_0=spidev
OF_COMPATIBLE_N=1
MODALIAS=spi:spidev
