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.

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.
