title: StarFive JH7110 AON Pin Controller

description: |
  Bindings for the JH7110 RISC-V SoC from StarFive Technology Ltd.

  Out of the SoC's many pins only the ones named PAD_RGPIO0 to PAD_RGPIO3
  can be multiplexed and have configurable bias, drive strength,
  schmitt trigger etc.
  Some peripherals such as PWM have their I/O go through the 4 "GPIOs".

          A pinctrl node should contain at least one subnode representing the
          pinctrl groups available on the machine. 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 enable/disable, slew-rate and drive strength.
