NAK on this based on how you are using pwm-fan in v10 discussion. See my
comments there.

Okay, I will merge everything from the pwm-fan0 node into the fan-0 node
and add the 'simple-bus' to the compatible string of the pwm_tach node.

What simple-bus has anything to do with it? This is not a bus. Just to
remind: we talk about bindings, not driver.

Hi Krzysztof,

If I want to create a dt-binding to indicate that the child nodes
should be treated as platform devices, which will be probed based on the
compatible string, can I add "simple-bus" for our pwm_tach node like the
following?
pwm_tach: pwm-tach-controller@1e610000 {
        compatible = "aspeed,ast2600-pwm-tach", "simple-bus";
        reg = <0x1e610000 0x100>;
        clocks = <&syscon ASPEED_CLK_AHB>;
        resets = <&syscon ASPEED_RESET_PWM>;
        #pwm-cells = <3>;
  
        fan-0 {
          tach-ch = /bits/ 8 <0x0>;
          compatible = "pwm-fan";
          pwms = <&pwm_tach 0 40000 0>;
        };
  
        fan-1 {
          tach-ch = /bits/ 8 <0x1 0x2>;
          compatible = "pwm-fan";
          pwms = <&pwm_tach 1 40000 0>;
        };
      };
Or do you have any other suggestions for describing this in the dt-bindings?

Thanks

Billy Tsai.
