| 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. | |

| The assignment to a function of an embedded peripheral is | |
| the responsibility of AT91 Pinctrl driver. This driver is | |
| responsible for the general-purpose I/O. | |

| config CMD_PCA953X | |
| bool "Enable the pca953x command" | |
| help | |
| Deprecated: This should be converted to driver model. | |
| This command provides access to a pca953x GPIO device using the | |
| legacy GPIO interface. Several subcommands are provided which mirror | |
| the standard 'gpio' command. It should use that instead. | |
| config PM8916_GPIO | |
| bool "Qualcomm PM8916 PMIC GPIO/keypad driver" | |

| 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. | |

| help | |
| DEPRECATED - This needs conversion to driver model | |
| This provides a way to looking at the pin state of this device. | |
| This mirrors the 'gpio' command and that should be used in preference | |
| to custom code. | |

| supported | |
| config MPC8XXX_GPIO | |
| bool "Freescale MPC8XXX GPIO driver" | |
| depends on DM_GPIO | |
| help | |
| This driver supports the built-in GPIO controller of MPC8XXX CPUs. | |
| Each GPIO bank is identified by its own entry in the device tree, | |
| i.e. | |
| gpio-controller@fc00 { | |
| #gpio-cells = <2>; | |
| compatible = "fsl,pq3-gpio"; | |
| reg = <0xfc00 0x100> | |
| } | |
| By default, each bank is assumed to have 32 GPIOs, but the ngpios | |
| setting is honored, so the number of GPIOs for each bank is | |
| configurable to match the actual GPIO count of the SoC (e.g. the | |
| 32/32/23 banks of the P1022 SoC). | |
| Aside from the standard functions of input/output mode, and output | |
| value setting, the open-drain feature, which can configure individual | |
| GPIOs to work as open-drain outputs, is supported. | |
