mpfgpio driver provides support for
the Microchip PolarFire SoC MSS GPIO controller.
The PolarFire SoC MSS has three GPIO units:
GPIO_1 control up to 14 and 24 IOs, respectively.
These IOs are routed through IOMUXes.
controls up to 32 IOs through the FPGA fabric.
The IOs can be configured as either inputs or outputs, and accessed using gpioctl(8).
