Support for the LPC32XX GPIO driver.

+config SANDBOX_GPIO
+ bool "Enable sandbox GPIO driver"
+ depends on SANDBOX && DM && DM_GPIO
+ 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.
+
+config SANDBOX_GPIO_COUNT
+ int "Number of sandbox GPIOs"
+ depends on SANDBOX_GPIO
+ default 128
+ 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.
