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 "LPC32XX GPIO driver"
22 Support for the LPC32XX GPIO driver.
25 bool "Enable sandbox GPIO driver"
26 depends on SANDBOX && DM && DM_GPIO
28 This driver supports some simulated GPIOs which can be adjusted
29 using 'back door' functions like sandbox_gpio_set_value(). Then the
30 GPIOs can be inspected through the normal get_get_value()
31 interface. The purpose of this is to allow GPIOs to be used as
32 normal in sandbox, perhaps with test code actually driving the
33 behaviour of those GPIOs.
35 config SANDBOX_GPIO_COUNT
36 int "Number of sandbox GPIOs"
37 depends on SANDBOX_GPIO
40 The sandbox driver can support any number of GPIOs. Generally these
41 are specified using the device tree. But you can also have a number
42 of 'anonymous' GPIOs that do not belong to any device or bank.
43 Select a suitable value depending on your needs.
46 bool "Vybrid GPIO driver"
50 Say yes here to support Vybrid vf610 GPIOs.
