Hi Linus,

To make sure I understand it correct, you think something like this is
OK?

	pinctrl@01c20800 {
		compatible = "mediatek,mt8135-pinctrl";
[...]
		pins-are-numbered;

		i2c0_pins_a: i2c0@0 {
			pins1 {
				pins = <MT8135_PIN_100_SDA0__FUNC_SDA0>,
					<MT8135_PIN_101_SCL0__FUNC_SCL0>;
				bias-disable;
			};
		};
[....]
	}
