description:
  The AST2700 features a dual-SoC architecture with two interconnected SoCs,
  each having its own System Control Unit (SCU) for independent pin control.
  This pin controller manages the pin multiplexing for SoC1.

  The SoC1 pin controller manages pin functions including eSPI, LPC and I2C,
  among others.

      Pin control state.

      If `function` is present, the node describes a pinmux state and must
      specify `groups`.

      For pin configuration, exactly one of `groups` or `pins` must be
      specified in each state node. Group-level configuration applies to all
      pins in the group. Pin-level configuration may be supplied in a
      separate state node for individual pins; when both group-level and
      pin-level configuration apply to the same pin, the pin-level
      configuration takes precedence.
