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 {
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_FULLNAME=/ahb/apb/spi@fc000000/spidev@0

Thanks,
