kgpio — Kernel
GPIO and DPIO driver
/dev/dpio/
The kgpio driver provides access to
general purpose and dedicated purpose I/O (GPIO and DPIO respectively)
devices that are built using the kernel's GPIO framework. See
gpio(7) for general background and an
overview of the system's design. GPIO controllers that are registered with
the framework are made available to the system through this driver. In
addition, when a DPIO is created, this driver is responsible for providing
that abstraction.
GPIO controllers, GPIO attributes, and the manipulation of DPIOs can be explored through the gpioadm(8) utility.
In general, the specific programming interfaces and
aspects of the kgpio driver are considered private
to the system and
Volatile,
subject to change without notice.
