That looks good, the IRQ is not shared. Can you test again with
IRQ_TYPE_EDGE_FALLING in the DT instead of IRQ_TYPE_LEVEL_LOW?
| can0: can@0 {
| reg = <0>;
| compatible = "microchip,mcp2515";
| pinctrl-names = "default";
| pinctrl-0 = <&can0_pin_irq>;
| interrupt-parent = <&pio>;
| interrupts = <6 8 IRQ_TYPE_EDGE_FALLING>;
You better use IRQ_TYPE_LEVEL_LOW instead of IRQ_TYPE_EDGE_FALLING, but
that's unrelated to this problem.
| clocks = <&can0_osc_fixed>;
| spi-max-frequency = <10000000>;
| gpio-controller;
| gpio-cells = <2>;
| status = "okay";
| };

Marc
