Simon Glassf94a1be2015-02-05 21:41:35 -070011 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.

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.

51 depends on DM_GPIO
52 help
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
56 for each bank.

59 bool "Enable sandbox GPIO driver"
60 depends on SANDBOX && DM && DM_GPIO
61 help
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.

69config SANDBOX_GPIO_COUNT
70 int "Number of sandbox GPIOs"
71 depends on SANDBOX_GPIO
72 default 128
73 help
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.
