I mean specific to this driver. With standard properties I mean those
you can add everywhere like pinctrl, interrupts etc. But then yes I
agree you can pretty quickly start to argue...

Would in this particular case something like


mcp2515: can@0 {
compatible = "microchip,mcp2515";
reg = <0>;
pinctrl-0 = <&pinctrl_can_int>;
pinctrl-names = "default";
clocks = <&clk16m>;
interrupt-parent = <&lsio_gpio3>;
interrupts = <13 IRQ_TYPE_EDGE_FALLING>;
spi-max-frequency = <10000000>;
};

be better?
