Ray Jui b64333ce76 pinctrl: cygnus: add gpio/pinconf driver
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

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
