  NXP Kinetis ACMP (Analog CoMParator)

  The following example displays the minimum node layout:

    acmp0: acmp@deadbeef {
            compatible = "nxp,kinetis-acmp";
            reg = <0xdeadbeef 0x1000>;
            interrupts = <0 0>;
            clocks = <&scg KINETIS_SCG_BUS_CLK>;
            status = "disabled";
    };

  Enabling the comparator node requires setting the minimum default
  configuration of the comparator. This includes selecting the
  positive and negative inputs, and routing them using pinctrl:

    &pinctrl {
            acmp0_default: acmp0_default {
                    group0 {
                            ...
                    };
            };
    };

    &acmp0 {
            status = "okay";
            pinctrl-0 = <&acmp0_default>;
            pinctrl-names = "default";

            positive-mux-input = "IN0";
            negative-mux-input = "IN1";
    };

compatible: "nxp,kinetis-acmp"
