+
+ 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.

+ help
+ 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
