This patch adds a DM GPIO driver for the Marvell MVEBU SoCs. There are other non-DM drivers that might be used on these platforms. But this patch creates a new DM driver. Which will be used by all Armada XP/38x boards. Other MVEBU SoC (Kirkwood / Orion) may follow once they support DM as well.

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.

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.

help
|

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 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.

|
|
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"

|
|
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.
