- 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.

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