2 # GPIO infrastructure and drivers
8 bool "Enable Driver Model for GPIO drivers"
11 Enable driver model for GPIO access. The standard GPIO
12 interface (gpio_get_value(), etc.) is then implemented by
13 the GPIO uclass. Drivers provide methods to query the
14 particular GPIOs that they provide. The uclass interface
15 is defined in include/asm-generic/gpio.h.
18 bool "DWAPB GPIO driver"
19 depends on DM && DM_GPIO
22 Support for the Designware APB GPIO driver.
25 bool "LPC32XX GPIO driver"
29 Support for the LPC32XX GPIO driver.
32 bool "Enable sandbox GPIO driver"
33 depends on SANDBOX && DM && DM_GPIO
35 This driver supports some simulated GPIOs which can be adjusted
36 using 'back door' functions like sandbox_gpio_set_value(). Then the
37 GPIOs can be inspected through the normal get_get_value()
38 interface. The purpose of this is to allow GPIOs to be used as
39 normal in sandbox, perhaps with test code actually driving the
40 behaviour of those GPIOs.
42 config SANDBOX_GPIO_COUNT
43 int "Number of sandbox GPIOs"
44 depends on SANDBOX_GPIO
47 The sandbox driver can support any number of GPIOs. Generally these
48 are specified using the device tree. But you can also have a number
49 of 'anonymous' GPIOs that do not belong to any device or bank.
50 Select a suitable value depending on your needs.
53 bool "Vybrid GPIO driver"
57 Say yes here to support Vybrid vf610 GPIOs.
