        description: |
          Enable digital filter. Set number of clock cycles to use as rejection
          threshold for input pulses. 0 disables the filter. Only valid for
          lpc11u6x SOC. Filter defaults to disabled, as this is default reset
          value for SOC

          set peripheral clock divider for input filter sampling clock
          IOCONCLKDIV. Only valid for lpc11u6x SOC. Default to 0, as this
          is the default reset value for the SOC.
      nxp,disable-analog-filter:
        type: boolean
        description: |
          Disable fixed 10 ns input glitch analog filter. Only valid for lpc11u6x
          SOC, on analog pins. Note that this filter is enabled on reset, hence
          the choice to make disabling the filter opt-in
