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.

40 depends on DM_GPIO
41 help
42 Support GPIO access on Rockchip SoCs. The GPIOs are arranged into
43 a number of banks (different for each SoC type) each with 32 GPIOs.
44 The GPIOs for a device are defined in the device tree with one node
45 for each bank.

48 bool "Enable sandbox GPIO driver"
49 depends on SANDBOX && DM && DM_GPIO
50 help
51 This driver supports some simulated GPIOs which can be adjusted
52 using 'back door' functions like sandbox_gpio_set_value(). Then the
53 GPIOs can be inspected through the normal get_get_value()
54 interface. The purpose of this is to allow GPIOs to be used as
55 normal in sandbox, perhaps with test code actually driving the
56 behaviour of those GPIOs.

58config SANDBOX_GPIO_COUNT
59 int "Number of sandbox GPIOs"
60 depends on SANDBOX_GPIO
61 default 128
62 help
63 The sandbox driver can support any number of GPIOs. Generally these
64 are specified using the device tree. But you can also have a number
65 of 'anonymous' GPIOs that do not belong to any device or bank.
66 Select a suitable value depending on your needs.
