How to enable imx8qxp-mek CAN in dts?

[Ale2]

I modify status in imx8x-mek.dtsi, imx-ss-dma.dtsi, imx8qxp-mek-rpmsg.dts to "okay".

&flexcan1 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_flexcan1>;
xceiver-supply = <&reg_can_stby>;
status = "okay";
};

But, the status is still "disabled" when I run kernel...

root@imx8qxpc0mek:/sys/firmware/devicetree/base/bus@5a000000/can@5a8d0000# cat status
disabled

root@imx8qxpc0mek:/sys/firmware/devicetree/base/bus@5a000000/can@5a8f0000# cat status
disabled

I wonder which .dts file control the status of CAN on MCIMX8QXP-CPU board. And, how to modify .dts file to register can0 on /dev?

Thank you!
