 config DM_GPIO
 	bool "Enable Driver Model for GPIO drivers"
 	depends on DM
 	help
-	  If you want to use driver model for GPIO drivers, say Y.
-	  To use legacy GPIO drivers, say N.
+	  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.

+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.
+
+config VYBRID_GPIO
+	bool "Vybrid GPIO driver"
+	depends on DM
+	help
+	  Say yes here to support Vybrid vf610 GPIOs.
