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 "Altera PIO driver"
21 Select this to enable PIO for Altera devices. Please find
22 details on the "Embedded Peripherals IP User Guide" of Altera.
25 bool "DWAPB GPIO driver"
26 depends on DM && DM_GPIO
29 Support for the Designware APB GPIO driver.
32 bool "ATMEL PIO4 driver"
36 Say yes here to support the Atmel PIO4 driver.
37 The PIO4 is new version of Atmel PIO controller, which manages
38 up to 128 fully programmable input/output lines. Each I/O line
39 may be dedicated as a general purpose I/O or be assigned to
40 a function of an embedded peripheral.
43 bool "LPC32XX GPIO driver"
47 Support for the LPC32XX GPIO driver.
50 bool "Rockchip GPIO driver"
53 Support GPIO access on Rockchip SoCs. The GPIOs are arranged into
54 a number of banks (different for each SoC type) each with 32 GPIOs.
55 The GPIOs for a device are defined in the device tree with one node
59 bool "Enable sandbox GPIO driver"
60 depends on SANDBOX && DM && DM_GPIO
62 This driver supports some simulated GPIOs which can be adjusted
63 using 'back door' functions like sandbox_gpio_set_value(). Then the
64 GPIOs can be inspected through the normal get_get_value()
65 interface. The purpose of this is to allow GPIOs to be used as
66 normal in sandbox, perhaps with test code actually driving the
67 behaviour of those GPIOs.
69 config SANDBOX_GPIO_COUNT
70 int "Number of sandbox GPIOs"
71 depends on SANDBOX_GPIO
74 The sandbox driver can support any number of GPIOs. Generally these
75 are specified using the device tree. But you can also have a number
76 of 'anonymous' GPIOs that do not belong to any device or bank.
77 Select a suitable value depending on your needs.
81 depends on ARCH_UNIPHIER
83 Say yes here to support UniPhier GPIOs.
86 bool "Vybrid GPIO driver"
90 Say yes here to support Vybrid vf610 GPIOs.
93 bool "Microchip PIC32 GPIO driver"
94 depends on DM_GPIO && MACH_PIC32
97 Say yes here to support Microchip PIC32 GPIOs.
