Enable driver model for GPIO access. The standard GPIO
|
|
|
|
|
interface (gpio_get_value(), etc.) is then implemented by
|
|
|
|
|
the GPIO uclass. Drivers provide methods to query the
|
|
|
|
|
particular GPIOs that they provide. The uclass interface
|
|
|
|
|
is defined in include/asm-generic/gpio.h.

The PIO4 is new version of Atmel PIO controller, which manages

up to 128 fully programmable input/output lines. Each I/O line
|
|
|
|
|
may be dedicated as a general purpose I/O or be assigned to
|
|
|
|
|
a function of an embedded peripheral.

This driver supports some simulated GPIOs which can be adjusted

GPIOs can be inspected through the normal get_get_value()

interface. The purpose of this is to allow GPIOs to be used as

normal in sandbox, perhaps with test code actually driving the

behaviour of those GPIOs.

The sandbox driver can support any number of GPIOs. Generally these
|
|
|
|
|
are specified using the device tree. But you can also have a number
|
|
|
|
|
of 'anonymous' GPIOs that do not belong to any device or bank.
|
|
|
|
|
Select a suitable value depending on your needs.
