| config DM_GPIO |
| bool "Enable Driver Model for GPIO drivers" |
| depends on DM |
| help |
| Enable driver model for GPIO access. The standard GPIO |
| interface (gpio_get_value(), etc.) is then implemented by |
| the GPIO uclass. Drivers provide methods to query the |
| particular GPIOs that they provide. The uclass interface |
| is defined in include/asm-generic/gpio.h. |
| |
| config ALTERA_PIO |
| bool "Altera PIO driver" |
| depends on DM_GPIO |
| help |
| Select this to enable PIO for Altera devices. Please find |
| details on the "Embedded Peripherals IP User Guide" of Altera. |

| config DWAPB_GPIO |
| bool "DWAPB GPIO driver" |
| depends on DM && DM_GPIO |
| default n |
| help |
| Support for the Designware APB GPIO driver. |
| |
| config ATMEL_PIO4 |
| bool "ATMEL PIO4 driver" |
| depends on DM |
| default n |
| help |
| Say yes here to support the Atmel PIO4 driver. |
| The PIO4 is new version of Atmel PIO controller, which manages |
| up to 128 fully programmable input/output lines. Each I/O line |
| may be dedicated as a general purpose I/O or be assigned to |
| a function of an embedded peripheral. |

| config LPC32XX_GPIO |
| bool "LPC32XX GPIO driver" |
| depends on DM |
| default n |
| help |
| Support for the LPC32XX GPIO driver. |
| |
| config ROCKCHIP_GPIO |
| bool "Rockchip GPIO driver" |
| depends on DM_GPIO |
| help |
| Support GPIO access on Rockchip SoCs. The GPIOs are arranged into |
| a number of banks (different for each SoC type) each with 32 GPIOs. |
| The GPIOs for a device are defined in the device tree with one node |
| for each bank. |
| |
| config SANDBOX_GPIO |
| bool "Enable sandbox GPIO driver" |
| depends on SANDBOX && DM && DM_GPIO |
| help |
| This driver supports some simulated GPIOs which can be adjusted |
| using 'back door' functions like sandbox_gpio_set_value(). Then the |
| GPIOs can be inspected through the normal get_get_value() |
| interface. The purpose of this is to allow GPIOs to be used as |
| normal in sandbox, perhaps with test code actually driving the |
| behaviour of those GPIOs. |
| |
| config SANDBOX_GPIO_COUNT |
| int "Number of sandbox GPIOs" |
| depends on SANDBOX_GPIO |
| default 128 |
| help |
| The sandbox driver can support any number of GPIOs. Generally these |
| are specified using the device tree. But you can also have a number |
| of 'anonymous' GPIOs that do not belong to any device or bank. |
| Select a suitable value depending on your needs. |
| |
| config VYBRID_GPIO |
| bool "Vybrid GPIO driver" |
| depends on DM |
| default n |
| help |
| Say yes here to support Vybrid vf610 GPIOs. |
