| 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. |

| 35 | Support GPIO access on Rockchip SoCs. The GPIOs are arranged into |
| 36 | a number of banks (different for each SoC type) each with 32 GPIOs. |
| 37 | The GPIOs for a device are defined in the device tree with one node |
| 38 | for each bank. |

| 43 | help |
| 44 | This driver supports some simulated GPIOs which can be adjusted |
| 45 | using 'back door' functions like sandbox_gpio_set_value(). Then the |
| 46 | GPIOs can be inspected through the normal get_get_value() |
| 47 | interface. The purpose of this is to allow GPIOs to be used as |
| 48 | normal in sandbox, perhaps with test code actually driving the |
| 49 | behaviour of those GPIOs. |

| 54 | default 128 |
| 55 | help |
| 56 | The sandbox driver can support any number of GPIOs. Generally these |
| 57 | are specified using the device tree. But you can also have a number |
| 58 | of 'anonymous' GPIOs that do not belong to any device or bank. |
| 59 | Select a suitable value depending on your needs. |
