This adds the initial support of the Broadcom Cygnus GPIO/PINCONF driver that supports all 3 GPIO controllers on Cygnus including the ASIU GPIO controller, the chipCommonG GPIO controller, and the always-on GPIO controller. Basic PINCONF configurations such as bias pull up/down, and drive strength are also supported in this driver. Pins from the ASIU GPIO controller can be individually muxed to GPIO function, through interaction with the Cygnus IOMUX controller Signed-off-by: Ray Jui <rjui@broadcom.com> Reviewed-by: Scott Branden <sbranden@broadcom.com> Tested-by: Dmitry Torokhov <dtor@chromium.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

Say Y here to support Broadcom BCM281xx pinctrl driver, which is used
|
|
for the BCM281xx SoC family, including BCM11130, BCM11140, BCM11351,
|
|
BCM28145, and BCM28155 SoCs. This driver requires the pinctrl
|
|
framework. GPIO is provided by a separate GPIO driver.

Say yes here to enable the Broadcom Cygnus GPIO driver.
|
|
|
|
The Broadcom Cygnus SoC has 3 GPIO controllers including the ASIU
|
|
GPIO controller (ASIU), the chipCommonG GPIO controller (CCM), and
|
|
the always-ON GPIO controller (CRMU/AON). All 3 GPIO controllers are
|
|
supported by this driver.
|
|
|
|
All 3 Cygnus GPIO controllers support basic PINCONF functions such
|
|
as bias pull up, pull down, and drive strength configurations, when
|
|
these pins are muxed to GPIO.
|
|
|
|
Pins from the ASIU GPIO can be individually muxed to GPIO function,
|
|
through interaction with the Cygnus IOMUX controller.

Say yes here to enable the Broadcom Cygnus IOMUX driver.
|
|
|
|
The Broadcom Cygnus IOMUX driver supports group based IOMUX
|
|
configuration, with the exception that certain individual pins
|
|
can be overrided to GPIO function
