In PIC32 GPIO controller is part of PIC32 pin controller. PIC32 has ten independently programmable ports and each with multiple pins. Each of these pins can be configured and used as GPIO, provided they are not in use for other peripherals.

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.

Say yes here to support the Atmel PIO4 driver.

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.

Support GPIO access on Rockchip SoCs. The GPIOs are arranged into
|
|
a number of banks (different for each SoC type) each with 32 GPIOs.

The GPIOs for a device are defined in the device tree with one node
|
|
for each bank.

help
|
|
This driver supports some simulated GPIOs which can be adjusted
|
|
using 'back door' functions like sandbox_gpio_set_value(). Then the
|
|
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.
