9 depends on DM
10 help
Simon Glassd8b771d2015-02-05 21:41:35 -0700[diff] [blame]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.

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.

44 depends on DM
45 help
46 This driver supports Broadwell U devices which have an expanded
47 GPIO feature set. The difference is large enough to merit a separate
48 driver from the common Intel ICH6 driver. It supports a total of
49 95 GPIOs which can be configured from the device tree.

63 Support GPIO controllers on Qualcomm Snapdragon family of SoCs.
64 This controller have single bank (default name "soc"), every
65 gpio has it's own set of registers.

85 help
86 Support GPIO access on Rockchip SoCs. The GPIOs are arranged into
87 a number of banks (different for each SoC type) each with 32 GPIOs.
88 The GPIOs for a device are defined in the device tree with one node
89 for each bank.

92 bool "Enable sandbox GPIO driver"
93 depends on SANDBOX && DM && DM_GPIO
94 help
95 This driver supports some simulated GPIOs which can be adjusted
96 using 'back door' functions like sandbox_gpio_set_value(). Then the
97 GPIOs can be inspected through the normal get_get_value()
98 interface. The purpose of this is to allow GPIOs to be used as
99 normal in sandbox, perhaps with test code actually driving the
100 behaviour of those GPIOs.

102config SANDBOX_GPIO_COUNT
103 int "Number of sandbox GPIOs"

105 default 128
106 help
107 The sandbox driver can support any number of GPIOs. Generally these
108 are specified using the device tree. But you can also have a number
109 of 'anonymous' GPIOs that do not belong to any device or bank.
110 Select a suitable value depending on your needs.
