+
+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_GPIO63
+ can be multiplexed and have configurable bias, drive strength,
+ schmitt trigger etc.
+ Some peripherals have their I/O go through the 64 "GPIOs". This also
+ includes a number of other UARTs, I2Cs, SPIs, PWMs etc.
+ All these peripherals are connected to all 64 GPIOs such that
+ any GPIO can be set up to be controlled by any of the peripherals.
