NAME

     amdgpio -- AMD GPIO Controller


SYNOPSIS

     amdgpio* at acpi?
     gpio* at gpiobus?


DESCRIPTION

     amdgpio provides a gpio(4) interface for the following AMD chipsets:

           AMD Ryzen 7 5800U with Radeon Graphics
           AMD Ryzen 7 8840HS with Radeon 780M Graphics

     The driver supports pin configuration flags

           GPIO_PIN_INPUT
           GPIO_PIN_OUTPUT
           GPIO_PIN_INOUT
           GPIO_PIN_ININ
           GPIO_PIN_PULLUP
           GPIO_PIN_PULLDOWN

     and interrupt capabilies

           GPIO_INTR_POS_EDGE
           GPIO_INTR_NEG_EDGE
           GPIO_INTR_DOUBLE_EDGE
           GPIO_INTR_HIGH_LEVEL
           GPIO_INTR_LOW_LEVEL
