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.

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.

This driver supports Broadwell U devices which have an expanded
|
|
GPIO feature set. The difference is large enough to merit a separate
|
|
driver from the common Intel ICH6 driver. It supports a total of
|
|
95 GPIOs which can be configured from the device tree.

Support GPIO controllers on Qualcomm Snapdragon family of SoCs.
|

This controller have single bank (default name "soc"), every
|
|
gpio has it's own set of registers.
|
|
Only simple GPIO operations are supported (get/set, change of
|
|
direction and checking pin function).
|
|
Supported devices:
|
|
- APQ8016
|
|
- MSM8916

Support GPIO access on Rockchip SoCs. The GPIOs are arranged into

a number of banks (different for each SoC type) each with 32 GPIOs.

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.

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.
