+         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.

+       help
+         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.
