          Each subnode will list the pins it needs, and how they should
          be configured, with regard to muxer configuration, bias, input
          enable/disable, input schmitt trigger, slew-rate, drive strength
          and bus hold state. In addition, all pins in the same subnode
          should have the same power domain. For configuration detail,
          refer to https://github.com/sophgo/sophgo-doc/.
