  Nordic nRF LPCOMP (analog Low-Power COMParator)

  The following example displays the minimum node layout:

    comp: comp@deadbeef {
            compatible = "nordic,nrf-lpcomp";
            reg = <0xdeadbeef 0x1000>;
            interrupts = <0 NRF_DEFAULT_IRQ_PRIORITY>;
            status = "disabled";
    };

  Enabling the comparator node requires setting the default
  configuration of the comparator.

  The following example displays enabling the comparator
  using an internal reference:

    &comp {
            status = "okay";
            psel = "AIN0";
            refsel = "VDD_4_8";
            enable-hyst;
    };

  To select an external reference, select the "AREF"
  reference and add the external reference:

    &comp {
            ...
            refsel = "AREF";
            extrefsel = "AIN1";
            ...
    };

compatible: "nordic,nrf-lpcomp"
