NAME #

mpfgpio - Microchip PolarFire SoC MSS GPIO controller

SYNOPSIS #

mpfgpio* at fdt? gpio* at mpfgpio?

DESCRIPTION #

The mpfgpio driver provides support for the Microchip PolarFire SoC MSS GPIO controller.

The PolarFire SoC MSS has three GPIO units: GPIO_0, GPIO_1 and GPIO_2. GPIO_0 and GPIO_1 control up to 14 and 24 IOs, respectively. These IOs are routed through IOMUXes. GPIO_2 controls up to 32 IOs through the FPGA fabric.

The IOs can be configured as either inputs or outputs, and accessed using gpioctl(8).

HISTORY #

The mpfgpio driver first appeared in OpenBSD 7.1.
