      KSI[7:0] does not support push-pull and open-drain mode.
      If KSO[17:0] is in KBS mode, setting 1 selects open-drain mode,
      setting 0 selects push-pull mode.
      If KSO[15:0] is in GPIO mode, then this bit is always disabled.

    type: int
    description: |
      If KSI[7:0]/KSO[15:0] is in KBS mode , setting 1 enables the internal
      pull-up (KSO[17:16] setting internal pull-up by GPIO port GPCR register).
      If KSI[7:0]/KSO[15:0] is in GPIO mode, then this bit is always disabled.

  gpio-group:
    type: boolean
    description: |
      Default setting pin configure to alternate mode for all GPIO group pins
      (include KSO[17:16]), otherwise setting pin configure to keyboard scan
      mode for KSI[7:0] and KSO[15:0] pins.
