| 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. | |
