Define fan in device tree

[alexander-kurichenko]

Hello,
I'm trying to define Argon One fan in device tree to control it directly from kernel (get a native support without using any scripts in userspace). As far as i know, there is a lot of different fan controllers on a market which are using i2c bus for PWM control. But I couldn't find anything related to this controller. Could you please give me more information regarding to your one?
Thank you in advance!

        fragment@0 {
                target = <&i2c1>;

                __overlay__ {

                        fan0: fan@0x1a {
                                compatible = ?????

                        };
                };
        };
