+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_GPIO0 to PAD_GPIO4
+  can be multiplexed and have configurable bias, drive strength,
+  schmitt trigger etc.
+  Some peripherals have their I/O go through the 4 "GPIOs". This also
+  includes PWM.
