| 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. |

| 62 | Support GPIO access on Rockchip SoCs. The GPIOs are arranged into |
| 63 | a number of banks (different for each SoC type) each with 32 GPIOs. |

| 70 | help |
| 71 | This driver supports some simulated GPIOs which can be adjusted |
| 72 | using 'back door' functions like sandbox_gpio_set_value(). Then the |
| 73 | GPIOs can be inspected through the normal get_get_value() |
| 74 | interface. The purpose of this is to allow GPIOs to be used as |
| 75 | normal in sandbox, perhaps with test code actually driving the |
| 76 | behaviour of those GPIOs. |
| 77 | |
| 78 | config SANDBOX_GPIO_COUNT |
| 79 | int "Number of sandbox GPIOs" |
| 80 | depends on SANDBOX_GPIO |
| 81 | default 128 |
| 82 | help |
| 83 | The sandbox driver can support any number of GPIOs. Generally these |
| 84 | are specified using the device tree. But you can also have a number |
| 85 | of 'anonymous' GPIOs that do not belong to any device or bank. |
| 86 | Select a suitable value depending on your needs. |
