Armbian for Rock 3A (unofficial build) with mainline kernel

ROCK 3 Series
45

Update 20220626
Armbian has disabled the pwm patch from legacy kernel: https://github.com/armbian/build/pull/3928. To make our pwm fan overlay work, there should be some modification: https://github.com/armbian/build/pull/3935. We have to replace the active to default. So the pwm fan overlay file should be like:

/dts-v1/;
/plugin/;

/ {
	compatible = "rockchip,rk3568";

	fragment@0 {
		target = <&pwm8>;

		__overlay__ {
			status = "okay";
			pinctrl-names = "default";
			pinctrl-0 = <&pwm8m0_pins>;
		};
	};
};
