menuconfig GPIO
bool "GPIO support"
default y
help
Enable support for GPIOs (General-purpose Input/Output) in U-Boot.
GPIOs allow U-Boot to read the state of an input line (high or
low) and set the state of an output line. This can be used to
drive LEDs, control power to various system parts and read user
input. GPIOs can be useful to enable a 'sign-of-life' LED,
for example. Enable this option to build the drivers in
drivers/gpio as part of an U-Boot build.

config DM_GPIO
bool "Enable Driver Model for GPIO drivers"
depends on DM

uration as part of the gpio-controller's driver probe function.
config DM_GPIO_LOOKUP_LABEL
bool "Enable searching for gpio labelnames"
depends on DM_GPIO
help

bool "Enable searching for gpio labelnames"
depends on DM_GPIO && SPL_DM && SPL_GPIO
help
This option enables searching for gpio names in

bool "AT91 PIO GPIO driver"
help

controller manages up to 32 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 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.

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.

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.
