| 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. |

| 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. |

| 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. |

| 66 | Only simple GPIO operations are supported (get/set, change of |

| 84 | help |
| 85 | This driver supports some simulated GPIOs which can be adjusted |
| 86 | using 'back door' functions like sandbox_gpio_set_value(). Then the |
| 87 | GPIOs can be inspected through the normal get_get_value() |
| 88 | interface. The purpose of this is to allow GPIOs to be used as |
| 89 | normal in sandbox, perhaps with test code actually driving the |
| 90 | behaviour of those GPIOs. |

| 92 | config SANDBOX_GPIO_COUNT |
| 93 | int "Number of sandbox GPIOs" |

| 95 | default 128 |
| 96 | help |
| 97 | The sandbox driver can support any number of GPIOs. Generally these |
| 98 | are specified using the device tree. But you can also have a number |
| 99 | of 'anonymous' GPIOs that do not belong to any device or bank. |
| 100 | Select a suitable value depending on your needs. |
