title: Phytium GPIO controller
|
|
|
|
description: |
|
|
Phytium GPIO controllers have one or two configurable ports, each of which
|
|
are intended to be represented as child nodes with the generic GPIO-controller
|
|
properties as desribed in this bindings file.

The interrupts to the parent controller raised when GPIOs generate

the interrupts. If the controller provides one combined interrupt
|
|
for all GPIOs, specify a single interrupt. If the controller provides
|
|
one interrupt for each GPIO, provide a list of interrupts that
|
|
correspond to each of the GPIO pins.
