+         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
