TCAN4550: TCAN4550RGYR

I will porting the tcan4550 & M_CAN driver in kernel 5.4.85

I have open m_can & tcan4x5x driver in menuconfig.

But i can't see the driver probe or init.

Can you help me check DTS setting & debug?

Thanks

Follow is my log.

~ # dmesg | grep -i can
[ 1.953941] CAN device driver interface

Follow is my DTS

ps. Do I need add "&m_can0" label in DTS ?

&spi2 {
  fsl,spi-num-chipselects = <0>;
  pinctrl-names = "default";
  pinctrl-0 = <&pinctrl_spi2_default &pinctrl_spi2cs1_default
    &pinctrl_spi2cs2_default &pinctrl_qspi2_default>;
  status = "okay";

  tcan4x5x: tcan4x5x@0 {
    mcompatible = "ti,tcan4x5x";
    reg = <0>;
    #address-cells = <1>;
    #size-cells = <1>;
    spi-max-frequency = <18000000>;
    bosch,mram-cfg = <0x0 0 0 32 0 0 1 1>;
    interrupt-parent = <&gpio1>;
    interrupts = <14 IRQ_TYPE_LEVEL_LOW>;
    reset-gpios = <&gpio1 27 GPIO_ACTIVE_LOW>;
};

};

Evan,

Thanks for bringing this to E2E. This Linux driver was developed by someone outside of our group, and unfortunately our team does not have experience supporting this driver. More information can be found at the following links, and this may be able to help you.

If you have any questions about how the TCAN4550-Q1 works once the Linux driver is established, we can absolutely help out. My apologies for any inconvenience.
